Abstract Using a solvothermal method, the metal-organic framework MOF(Ni)-74 and a series of its derivatives MOF(Ni)-GO(w%) differing in graphene oxide (GO) content (w%) were synthesized, and subsequently the linear sweep voltammetry (LSV) test was conducted in a N₂-saturated 0.5 mol/L H₂SO₄ solution in order to determine the electrocatalytic performance of the products to hydrogen evolution reaction (HER). Our experiment confirmed the significantly improved electrocatalytic activity of the GO-decorated MOF(Ni)-74 catalysts, among which the MOF(Ni)-GO(8%) exhibited the best electrochemical catalytic performance towards HER with the lowest onset potential (-0.462 V), the smallest Tafel slope (110 mV/dec), as well as an excellent electrochemical stability.
