Abstract
Transition metal single-atom catalysts (SACs) in uniform carbon nanospheres have gained tremendous interest as electrocatalysts owing to their low cost, high activity, and excellent selectivity. However, their preparation typically involves complicated multistep processes that are not practical for industrial use. Herein, we report a facile one-pot method to produce atomically isolated metal atoms with high loadings in uniform carbon nanospheres without any templates or postsynthesis modifications. Specifically, we use a chemical confinement strategy to suppress the formation of metal nanoparticles by introducing ethylenediaminetetraacetic acid (EDTA) as a molecular barrier to spatially isolate the metal atoms and thus generate SACs. To demonstrate the versatility of this synthetic method, we produced SACs from multiple transition metals, including Fe, Co, Cu, and Ni, with loadings as high as 3.87 wt %. Among these catalytic materials, the Fe-based SACs showed remarkable catalytic activity toward the oxygen reduction reaction (ORR), achieving an onset and half-wave potential of 1.00 and 0.831 VRHE, respectively, comparable to that of commercial 20 wt % Pt/C. Significantly, we were able to steer the ORR selectivity toward either energy generation or hydrogen peroxide production by simply changing the transition metal in the EDTA-based precursor.

Abstract
We report a robust method for the facile synthesis of N-doped carbon nanospheres with uniform and tunable sizes. Instead of involving a surfactant or other templates, this synthesis relies on the incorporation of ethylenediaminetetraacetic acid (EDTA) into the emulsion droplets of phenolic resin oligomers. The EDTA provides a high density of surface charges to effectively increase the electrostatic repulsion between the droplets and thereby prevent them from coalescing into irregular structures during polymerization-induced hardening. The EDTA-loaded polymer nanospheres are highly uniform in terms of both size and shape for easy crystallization into opaline structures. While maintaining good uniformity, the diameters of the resultant N-doped carbon nanospheres can be readily tuned from 100 to 375 nm, allowing for the fabrication of opaline lattices with brilliant structural colors. The EDTA also serves as an additional nitrogen source to promote the formation of graphitic-N, making the N-doped carbon nanospheres highly active, metal-free bifunctional electrocatalysts toward oxygen reduction and oxygen evolution reactions.

Abstract
Environmental pollution has worsened as a result of antibiotic overuse. Nitrogen doping of biochar increases its ability to adsorb antibiotics and has been widely applied as an adsorbent. In this study, we synthesized nitrogen-doped biochar (N-A) from cocoa shell wastes calcined with urea and sodium bicarbonate (NaHCO3) as nitrogen sources and green activators, respectively. An analysis of the biochar morphology, structure, specific surface area, and functional groups provided an understanding of its properties. As indicated by increased surface area, micropores, and surface functional groups, biochar was enhanced in its performance for norfloxacin adsorption when activated using NaHCO3 and nitrogen doped. Adsorption experiments revealed that N-A biochar at 700 and 400 °C had a high adsorption capacity for NOR of 134 mg/g (N-A-CSB700) and 112.31 mg/g (N-A-CSB400) when compared to pristine biochar at 59.27 mg/g (CSB700) and 56.34 mg/g (CSB400), indicating that N-A doped modification on biochar greatly improved adsorption capacity. The Langmuir model demonstrated better NOR adsorption isotherms. The pseudo-second order and Elovich models closely followed the adsorption kinetics. Further investigations were conducted to determine how environmental factors influence biochar interaction with NOR. The results indicated a stable NOR removal efficiency was kept at a wide pH range, whereas the ionic strength inhibited the NOR adsorption process. The investigation into the sorption mechanism revealed that pore filling, H-bonding, π-π EDA interactions, ion exchange, and electrostatic attraction may all be implicated in the NOR adsorption process. Specifically, pore filling played the dominant role for N-A-CSB700, while N-A-CSB400 sorption occurred mainly via H-bonding. Since N-A-CSB700 doped biochar combines high adsorption capacity with a low inhibition effect of environmental factors (Na+/Ca2+), it has a high potential for future practical applications as an environmentally sustainable alternative. It uses low-cost solid waste to produce an adsorbent to cope with emerging contaminants such as antibiotics.

Abstract
Contamination of phenolic compounds has devastating effects on the environment. Therefore, its harmless treatment and recycling have received extensive attention. Herein, a novel method for preparing N-S doped phenolic resin (NSPR) from phenols, N and S groups in semi-coking wastewater, and formaldehyde are developed. The KOH is consequently incorporated into the NSPR through simultaneous carbonization and activation in a single step to produce porous carbon material (NSPC). The as-obtained NSPC exhibits a high specific capacitance of 182 F g-1 at 0.5 A g-1, a high energy density of 9.1 Wh kg-1 at a power density of 0.15 kW kg-1, and remarkable cycling stability in aqueous KOH electrolyte. This outstanding electrochemical performance is attributed to its ultrahigh specific surface area (SSA, 2,523 m2 g-1), enormous total pore volume (Vt, 1.30 cm3 g-1), rational pore structure, and N-S heteroatom self-doping (0.76 at% N and 0.914 at% S), which ensures adequate charge storage, rapid electrolyte ion diffusion, and contributed pseudo-capacitance. This work not only provides a facile method for transforming phenolic wastewater into high-value products but also offers a cost-effective and high-performance porous carbon material for supercapacitors.

Abstract
Biomass is a common carbon precursor, because of its low cost, easy access and wide sources. However, direct pyrolysis of biomass usually leads to some disadvantages such as morphology destruction, low surface area and poor porosity. Herein, a silica-confined activation strategy is developed to prepare nitrogen-doped (N-doped) porous carbon microcapsule using the renewable biomass carbon precursor of yeasts. The yeasts are wrapped by a dense silica shell, forming a limited space, which can effectively avoid the destruction of yeast morphology during pyrolysis. The pyrolysis gas derived from yeast cannot overflow due to the limitation of confined space, and it plays an in-situ activator to result in layer structure with thin wall, abundant pores and high specific surface area (870 m2 g-1). Moreover, the N-doped porous carbon microcapsule possesses a higher certain of N-doping than the carbon product derived from direct pyrolysis of yeasts. As electrode materials in supercapacitor, the N-doped porous carbon microcapsule exhibits high capacitance of 316 F g-1 at 1 A g-1 with obvious enhancement of electrochemical performance compared with the carbon product derived from direct pyrolysis of yeasts, indicating the promise as a new electrode material in energy storage.

Abstract
The Stöber method is a highly efficient synthesis strategy for homogeneous monodisperse polymer colloidal spheres and carbon spheres. This work delivers an extended Stöber method and investigates the synthesis process. By calcining the precursor under appropriate conditions, solid secondary particles of amorphous carbon (SSAC) and hollow secondary particles of graphitized carbon (HSGC) can be directly synthesized. The two materials have a nano-primary particle structure and a closely-packed sub-micron secondary particle structure, which can be used in energy storage. We find that SSAC and HSGC have high potassium-ion storage capacity with reversible capacities of 274 mA h g-1 and 283 mA h g-1 at 20 mA g-1 respectively. Significantly, SSAC has better rate performance with a specific capacity of 107 mA h g-1 at 1 A g-1.

Abstract
Nitrogen-doped hierarchical porous carbons with a rich pore structure were prepared via direct carbonization of the poly(ionic liquid) (PIL)/potassium ferricyanide compound. Thereinto, the bisvinylimidazolium-based PIL was a desirable carbon source, and potassium ferricyanide as a multifunctional Fe-based template, could not only serve as the pore-forming agent, including metallic components (Fe and Fe3C), potassium ions (etching carbon framework during carbonization), and gas generated during the pyrolysis process, but also introduce the N atoms to porous carbons, which were in favor of CO2 capture. Moreover, the hierarchically porous carbon NDPC-1-800 (NDPC, nitrogen-doped porous carbon) had taken advantage of the highest specific surface area, exhibiting an excellent CO2 adsorption capacity and selectivity compared with NDC-800 (NDC, nitrogen-doped carbon) directly carbonized from the pure PIL. Furthermore, its hierarchical porous architectures played an important part in the process of CO2 capture, which was described briefly as follows: the synergistic effect of mesopores and micropores could accelerate the CO2 molecules' transportation and storage. Meanwhile, the appropriate microporous size distribution of NDPC-1-800 was conducive to enhancing CO2/N2 selectivity. This study was intended to open up a new pathway for designing N-doped porous carbons combining both PILs and the multifunctional Fe-based template potassium ferricyanide with wonderful gas adsorption and separation performance.

Abstract
Hierarchically nanoporous carbon materials (HNCMs) with well-defined morphology and excellent electrochemical properties are promising in fabrication of energy storage devices. In this work, we made a comparative study on the supercapacitive performances of HNCMs with different morphologies. To this end, four types of HNCMs with well-defined morphologies including submicrospheres (HNCMs-S), hexagonal nanoplates (HNCMs-N), dumbbell-like particles (HNCMs-D), and hexagonal microprisms (HNCMs-P) were successfully synthesized by dual-template strategy. The relationship of structural-electrochemical property was revealed by comparing the electrochemical performances of these HNCMs-based electrodes using a three-electrode system. The results demonstrated that the HNCMs-S-based electrode exhibited the highest specific capacitance of 233.8 F g-1 at the current density of 1 A g-1 due to the large surface area and well-defined hierarchically nanoporous structure. Moreover, the as-prepared HNCMs were further fabricated into symmetrical supercapacitor devices (HNCMs-X//HNCMs-X) using KOH as the electrolyte and their supercapacitive performances were checked. Notably, the assembled HNCMs-S//HNCMs-S symmetric supercapacitors displayed superior supercapacitive performances including high specific capacitance of 55.5 F g-1 at 0.5 A g-1, good rate capability (retained 71.9% even at 20 A g-1), high energy density of 7.7 Wh kg-1 at a power density of 250 W kg-1, and excellent cycle stability after 10,000 cycles at 1 A g-1. These results further revealed the promising prospects of the prepared HNCMs-S for high-performance energy storage devices.
