CoP-entrapped, P-doped mesoporous carbons prepared from phenolic resin with CoCl2 as template for hydrogen evolution

In order to replace the Pt catalyst which has several limitations that hampered the corresponding practical applications. A series of mesoporous carbons encapsulating CoP nano-particles and doped with P were prepared by a combination of solvent-evaporation-induced self-assembly (EISA) and carbonization. Phenolic-based resins and diammonium hydrogen phosphate as carbon and phosphorus precursors, respectively. Cobalt chloride hexahydrate (CoCl2) 2 ) was used as the cobalt precursor, which was also treated as the porogen. Based on characterization data, the porosity of the final sample depends on the amount of CoCl2 2 added. which could further determine the electrocatalytic activity. When evaluated as the electrocatalysts towards hydrogen evolution reaction (HER), the as-received electrocatalysts exhibited outstanding electrocatalytic performance, including low overpotential, small Tafel slope, and good stability.
