Dinuclear cobalt complexes have been prepared that model the edge sites of heterogeneous cobalt-based catalysts that perform the oxygen evolution and reduction reactions (OER and ORR, respectively). For the former, binding studies to the dinuclear copper sites capture the mechanistic elements of the proton-coupled electron transfer (PCET) reaction of the heterogeneous catalysts and establish the necessity of dinuclear cobalt edge sites for OER catalysis. In the case of ORR, the edge sites are also the key to efficient and selective oxygen to water ORR.
