Designing a hybrid nanomaterial based on Cr-containing polyoxometalate and graphene oxide as an electrocatalyst for the hydrogen evolution reaction

A polyoxometalate (POM)-based hybrid nanomaterial is designed via covalent interaction between the Cr(acac) 3 complex and [PMo 11 O 39 ] 7− , followed by immobilization on the surface of modified graphene oxide (mGO) for the hydrogen evolution reaction.
