Development of polyoxometalate-based Ag-H2biim inorganic–organic hybrid compounds functionalized for the acid electrocatalytic hydrogen evolution reaction

Two POM-based Ag-H 2 biim inorganic–organic hybrid compounds undergoing electrochemical surface restructuring can efficiently and robustly catalyze the hydrogen evolution reaction in 0.5 M H 2 SO 4 with low overpotential and good long-term stability.
