Summary: In this study, a series of ordered mesoporous carbon (OMC) electrodes with switchable surface wettability were developed. These electrodes are favorable for water electrolysis at high current densities and increase the production of H2O2 in the oxygen reduction reaction. The hydrophilic OMC electrodes can promote the oxygen evolution reaction performance by separating O2 bubbles promptly, while the hydrophobic OMC electrodes provide a directional diffusion channel for O2 transport to improve the efficiency of O2 utilization. These electrodes are expected to play an important role in electrocatalytic reactions involving gases.

Summary: An etching-functionalization strategy was developed to construct a tannic-acid-functionalized MOF with a unique hollow-wall and 3D-ordered macroporous structure. This MOF can be further used as a precursor for the synthesis of cobalt supported on oxygen/nitrogen co-doped carbon composites with H-3DOM structures and hydrophilic surface. The resulting catalyst exhibits high electrocatalytic activity in the oxygen reduction reaction.

Summary: By utilizing a metal-ligand coordination assisted-self-assembly approach, three gold nanoparticles were successfully encapsulated in ordered mesoporous carbon with large pores and thick pore walls. The strong coordination between the gold species and the mercapto groups, as well as the thick porous walls, contribute to the dispersion and stability of the gold nanoparticles at high temperatures and their reactivity and stability in water.

Summary: Iron-nitrogen moieties encapsulated in N-doped graphitic and hierarchical biochars were derived from hydrothermal pyrolysis and microwave NH3 activation of cellulose and lignin, with cellulose-derived biochars showing superior activities in oxygen reduction reaction (ORR) compared to lignin-derived biochars. Among them, the C-1% biochar exhibited the best electrocatalytic performance and followed a near four-electron ORR route, attributed to the active iron-nitrogen sites covered with hierarchical carbon shells. The incorporation of iron-nitrogen in cellulose-derived biochars through a time-saving and energy-efficient microwave activation procedure may have potential applications in ORR.

Summary: This study demonstrates the growth of CsPbBr3 nanoparticles on semiconducting graphene oxide and conductive few-layer graphene surfaces, showing different interfacial charge transfer behaviors. The rate constant of charge transfer can be modulated by controlling the composition ratio of graphene oxide and few-layer graphene. The relationship between CO2 to CH4 conversion rate and charge transfer rate differs between the graphene oxide-based and few-layer graphene-based nanoheterostructures. This work provides important insights for the design of perovskite-graphene based nanoheterostructures with remarkable performance for solar-driven CO2 conversion.
