redox flow batteries. Science 2021; 372:836-840.

Abstract
Aqueous redox flow batteries with organic active materials offer an
environmentally benign, tunable, and safe route to large-scale energy
storage. Development has been limited to a small palette of organics that
are aqueous soluble and tend to display the necessary redox reversibility
within the water stability window. We show how molecular engineering of
fluorenone enables the alcohol electro-oxidation needed for reversible
ketone hydrogenation and dehydrogenation at room temperature without the use
of a catalyst. Flow batteries based on these fluorenone derivative anolytes
operate efficiently and exhibit stable long-term cycling at ambient and
mildly increased temperatures in a nondemanding environment. These results
expand the palette to include reversible ketone to alcohol conversion but
also suggest the potential for identifying other atypical organic redox
couple candidates.

Abstract
This work is based on various bio-reduction of graphene oxide into reduced graphene oxide and their applications in organic synthesis and group transformations. Graphene oxide, with abundant oxygencontaining functional groups on its basal plane, provides potential advantages, including excellent dispersibility in solvents and the good heterogeneous catalyst. This manuscript reviews various methods of synthesis of graphene and graphene oxide and a comparative study on their advantages and disadvantages, how to overcome disadvantages and covers extensive relevant literature review. In the last few years, investigation based on replacing the chemical reduction methods by some bio-compatible, chemical/impurity-free rGO including flash photo reductions, hydrothermal dehydration, solvothermal reduction, electrochemical approach, microwave-assisted reductions, light and radiation-induced reductions has been reported. Particularly, plant extracts have been applied significantly as an efficient reducing agent due to their huge bioavailability and low cost for bio-reduction of graphene oxide. These plant extracts mainly contain polyphenolic compounds, which readily get oxidized to the corresponding unreactive quinone form, which are the driving force for choosing them as bio-compatible catalyst. Currently, efforts are being made to develop biocompatible methods for the reduction of graphene oxide. The reduction abilities of such phytochemicals have been reported in the synthesis and stabilization of various nanoparticles viz. Ag, Au, Fe and Pd. Various part of plant extract has been applied for the green reduction of graphene oxide. Furthermore, the manuscript describes the catalytic applications of graphene oxide and reduced graphene oxide nanosheets as efficient carbo-catalysts for valuable organic transformations. Herein, important works dedicated to exploring graphene-based materials as carbocatalysts, including GO and rGO for organic synthesis including various functional group transformations, oxidation, reduction, coupling reaction and a wide number of multicomponent reactions have been highlighted. Finally, the aim of this study is to provide an outlook on future trends and perspectives for graphene-based materials in metal-free carbo-catalysis in green synthesis of various pharmaceutically important moieties.

Abstract
Metal-free reaction conditions featuring oxygen and 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) were employed for the selective oxidation of benzyl amines and active methylene compounds to afford various amides and ketones. Owing to the strong basicity of guanidine bases, TBD is presumed to play an important role in the cleavage of the C-H bond at the benzylic position of peroxide intermediates, which were formed by the reaction with oxygen.

Abstract
Since Geim and co-workers reported their groundbreaking experiments on graphene, research on
graphene oxide (GO) and its derivatives has greatly influenced the field of modern physics, chemistry, device
fabrication, material science, and nanotechnology. The unique structure and fascinating properties of these carbon
materials can be ascribed to their eminent chemical, electronic, electrochemical, optical, and mechanical
properties of GO and its derivatives, particularly compared to other carbon allotropes. The present Review
aims to provide an overview on the recent developments in the preparation of GO and its derivatives and their
applications in organic reactions. We will first outline the synthesis of GO and its derivatives. Then, we will
discuss the major sections about their application as stoichiometric and catalytic oxidants in organic reactions,
a particular emphasis on the carbon-carbon, carbon-oxygen, and carbon-nitrogen single bond-forming reactions,
as well as carbon-oxygen and carbon-nitrogen double bond-forming reactions. Simultaneously, this Review
also describes briefly transition metal supported on GO or its derivatives as a catalyst for organic reaction.
Lastly, we will present an outlook of potential areas where GO and its derivatives may be expected to find
utility or opportunity for further growth and study.

Abstract
Porous solid bases are increasingly attractive for applications in green chemistry and heterogeneous catalysis under relatively mild conditions. Here, covalent triazine frameworks (CTFs) were first applied as a support for the porous solid strong bases through a redox process between the base precursor KNO3 and CTFs, leading to a relatively low calcination temperature (400 °C). As a result, porous organic frameworks possessing ordered microstructures as well as strong basic sites were successfully synthesized. The materials were characterized by X-ray diffraction, Fourier transform infrared, high-resolution transmission electron microscopy, temperature programmed desorption of CO2, and so forth. The obtained solid bases displayed remarkable catalytic activity in the aerobic oxidation of methylene compounds, and the yield of fluorenones could reach 93.6% at 120 °C, which was nearly 3 times higher than that of the control catalyst. The current research may present a new idea for the construction of porous organic polymers with strong basicity.

Abstract
We present a simple co-precipitation method to prepare highly nanoporous YBO(3) architecture using NaBO(3) · 4H(2)O as a boric source and 600°C as the annealing temperature. The reaction was carried out under an aqueous condition without any organic solvent, surfactant, or catalysts. The prepared samples were characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The photoluminescence of doped-nanoporous YBO(3):Eu(3+) was further investigated. It is expected that highly nanoporous YBO(3) architecture can be an ideal candidate for applications in catalysis, adsorption, and optoelectronic devices.

Abstract
We demonstrate a simple method to prepare high-quality and uniform three-dimensional (3D) graphene networks through thermal degradation of graphene oxide (GO)-nitrocellulose composites over a large area. The nitrocellulose simultaneously acts as a support and aids in the reduction of GO by exothermic decomposition. The graphene networks have tunable porous morphology where the pore size can be controlled by adjusting the concentration of GO in the composite. This new technique is a very simple method to obtain 3D graphene networks and has the potential to produce 3D graphene-modified substrates for use in energy storage and conversion applications, in supporting frameworks of catalyst, and in sensors. In this report, the prepared 3D graphene networks were directly used as the electrodes of supercapacitors without using a binding agent and/or conducting additive with a high specific capacitance of 162.5 F g(-1) at 0.5 A g(-1) current density.
