An hourglass-shaped nickel-based polyoxometalate crystalline material as a highly efficient bifunctional electrocatalyst for the oxygen evolution reaction and detection of H2O2

A novel P 4 Mo 6 -based POMOFs (CUST-576) was synthesized as a pre-catalyst in the OER reaction, and NiOOH, Ni(OH) 2 obtained by in situ reconstruction was used as the main active site with good electrocatalytic OER and H 2 O 2 detection performance.
