“…Among the produced nanostructures, the hierarchical nanostructure has a higher electrocatalytic activity. 203 The hierarchical nanostructure needs overpotentials of 231 mV (HER) and 300 mV (OER) to produce a current density of 10 mA cm −2 . Xiong et al 204 developed a method of cobalt covalent doping that can induce HER and OER bifunctionality in MoS 2 for effective overall water splitting.…”

A simple hydrothermal approach was used to obtain boat‐, cuboid‐, and dumbbell‐shaped hierarchical morphology of cerium (IV) hydroxidophosphate materials. The period of the reactions, pH, and types of bases play crucial roles in tuning the morphology of the material. PXRD, FE‐SEM, HR‐TEM, FT‐IR, XPS, EDX, and EPR spectroscopies were used to analyze the materials. FE‐SEM and HR‐TEM analysis show that the materials have hierarchical morphology. According to XPS and EPR analysis, the materials comprise a redox‐active Ce3+/Ce4+ couple. The thiol to disulfide oxidative coupling reaction is synergistically boosted by the hierarchical morphology and redox‐active Ce3+/Ce4+ couple. The catalyst has excellent catalytic activity both in aqueous as well as protic organic solvents. However, the catalyst exhibited no reactivity in common organic solvents such as CH3CN, DCM, and THF. The catalytic reaction was thoroughly investigated in the presence of various solvents, catalyst amounts, oxidising agents, and substrates. In the presence of H2O2, the yield is 99%, whereas in the presence of air, it is 79%. We found high yields for several aromatic thiols but aliphatic thiols exhibited relatively poor yields under identical conditions.
