Abstract
The consumption of electrical energy grows alongside the development of global industry. Generating energy storage has become the primary focus of current research, examining supercapacitors with high power density. The primary raw material used in supercapacitor electrodes is activated carbon (AC). To improve the performance of activated carbon, we used manganese dioxide (MnO2), which has a theoretical capacitance of up to 1370 Fg-1. The composite-based activated carbon with a different mass of 0-20% MnO2 was successfully introduced as the positive electrode. The asymmetric cell supercapacitors based on activated carbon as the anode delivered an excellent gravimetric capacitance, energy density, and power density of 84.28 Fg-1, 14.88 Wh.kg-1, and 96.68 W.kg-1, respectively, at 1 M Et4NBF4, maintaining 88.88% after 1000 test cycles.

MXene/Ferrite Magnetic Nanocomposites for Electrochemical Supercapacitor Applications. MICROMACHINES 2022; 13:1792. [PMID: 36296145 PMCID: PMC9611495 DOI: 10.3390/mi13101792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 10/07/2022] [Accepted: 10/18/2022] [Indexed: 06/16/2023]
Abstract
MXene has been identified as a new emerging material for various applications including energy storage, electronics, and bio-related due to its wider physicochemical characteristics. Further the formation of hybrid composites of MXene with other materials makes them interesting to utilize in multifunctional applications. The selection of magnetic nanomaterials for the formation of nanocomposite with MXene would be interesting for the utilization of magnetic characteristics along with MXene. However, the selection of the magnetic nanomaterials is important, as the magnetic characteristics of the ferrites vary with the stoichiometric composition of metal ions, particle shape and size. The selection of the electrolyte is also important for electrochemical energy storage applications, as the electrolyte could influence the electrochemical performance. Further, the external magnetic field also could influence the electrochemical performance. This review briefly discusses the synthesis method of MXene, and ferrite magnetic nanoparticles and their composite formation. We also discussed the recent progress made on the MXene/ferrite nanocomposite for potential applications in electrochemical supercapacitor applications. The possibility of magnetic field-assisted supercapacitor applications with electrolyte and electrode materials are discussed.

Noble Metal-Based Catalysts with Core-Shell Structure for Oxygen Reduction Reaction: Progress and Prospective. NANOMATERIALS 2022; 12:nano12142480.

Abstract
With the deterioration of the ecological environment and the depletion of fossil energy, fuel cells, representing a new generation of clean energy, have received widespread attention. This review summarized recent progress in noble metal-based core–shell catalysts for oxygen reduction reactions (ORRs) in proton exchange membrane fuel cells (PEMFCs). The novel testing methods, performance evaluation parameters and research methods of ORR were briefly introduced. The effects of the preparation method, temperature, kinds of doping elements and the number of shell layers on the ORR performances of noble metal-based core–shell catalysts were highlighted. The difficulties of mass production and the high cost of noble metal-based core–shell nanostructured ORR catalysts were also summarized. Thus, in order to promote the commercialization of noble metal-based core–shell catalysts, research directions and prospects on the further development of high performance ORR catalysts with simple synthesis and low cost are presented.

JOURNAL OF HAZARDOUS MATERIALS 2021; 410:124643.

Abstract
Fe-C micro-electrolysis system has been widely used in filters, or as an advanced treatment process in some water treatment plants to treat various wastewater. In this study, Fe-C micro-electrolysis process was enhanced by an economical and environmentally friendly method, applied magnetic field. Batch kinetic experiments and scanning electron micrographs demonstrated a more effective micro-electrolysis and more severely corroded on the surface of Fe-C after applying a magnetic field at pH 3.0. An applied magnetic field reduced the charge-transfer resistance and increased the current density in micro-electrolysis system and Fe-C became more prone to electrochemical corrosion. Corrosion products were proved to be Fe2+, Fe3O4, and C-O, moreover, the formation of them were also increased in the presence of a magnetic field. Base on that, some influential factors like magnetic field flux intensity, Fe-C particle size, pH, Fe-C dosage and its reusability were investigated in this paper. Since Fe2+ release was accelerated in micro-electrolysis system by an applied magnetic field, combination of various advanced oxidation processes were designed to explore the application effectiveness of the system. The degradation rate of target contaminant was significantly improved in the presence of a magnetic field, suggesting it could be a reliable method for wastewater treatment.

Abstract
Al3Ni and Al3Ti alloys were prepared by arc melting and exposed to chemical leaching in 5M NaOH at room temperature. In case of Al3Ni alloy, Al reached phases react with the leaching solution to produce nanoporous nickel with a pore diameter in the range of ~10–20 nm. Only pure Al phase of Al3Ti alloy chemically reacts with the production of a dense wrinkled surface with a wrinkle size of ~50–100 nm.
