Question

Mn2o3for electrochemical oxygen evolution reaction

Answer 1

A bare WO3 electrode and a WO3 electrode coupled with a layer of Co− Pi oxygen evolution catalyst (OEC) were prepared to investigate the effect of Co− Pi OEC on the selectivity of photo-oxidation reactions and photostabilities of WO3 photoanodes. WO3 photoanodes have been reported to produce peroxo species as well as O2 during photo-oxidation reactions, and the accumulation of peroxo species on the surface is known to cause a gradual loss of photoactivity of WO3. The photocurrent to O2 conversion efficiencies of the …
