Preparation and electrocatalytic performance of MoSe2/Co-MOF/NF for oxygen evolution reaction
Designing efficient oxygen evolution reaction(OER)catalysts is crucial for water splitting to produce hydrogen.Based on the catalytic activity of transition metal selenides(TMSe)and the structural characteristics of metal-organic frameworks(MOFs),the work proposed a strategy to compound MOFs and TMSe.The composite mate-rial grew on conductive base nickel foam(NF)inherited the advantages of the two materials,and the defects of poor conductivity of MOFs and easy aggregation of TMSe were effectively improved.The MoSe2/Co-MOF/NF showed excellent electrochemical performance in alkaline solution,and its overpotential was only 242 mV at 10 mA·cm-2,the Tafel slope was 50.64 mV·dec-1.In addition,it exhibited good stability in an alkaline solution after 1 000 cyclic voltammetry(CV)cycles and 30 h constant voltage electrolysis test.
