Harnessing the cobalt complex for bidirectional O2/H2O transformation in neutral water via electrocatalysis/photocatalysis

Bidirectional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) catalysts are crucial for renewable energy transduction via electrolyzers and fuel cell. Here, we present a protocol for harnessing the cobalt complex for bidirectional O2/H2O transformation in neutral water via electrocatalysis/photocatalysis. We describe steps for monitoring ORR and OER in neutral aqueous solution, measuring O2 concentration, and identifying the probable catalytic mechanism for ORR and OER. We then detail procedures for examining catalyst behavior under photocatalytic conditions in neutral aqueous surroundings.For complete details on the use and execution of this protocol, please refer to Saini et al.1
