A polyoxometalate-anchored Ni MOF for high-efficiency, selective H 2 O 2 electrosynthesis

FeMo 6 clusters anchored on a Ni MOF with coordinatively unsaturated Ni sites steer the 2e − ORR to 94.3% H 2 O 2 selectivity at 0.72 V vs. RHE with 169.81 mmol g cat −1 h −1 productivity and >50 000 s stability.
