What is ZnO as an Active and Selective Catalyst for Electrochemical Water Oxidation to Hydrogen Peroxide about?
Electrochemical synthesis of hydrogen peroxide (H 2 O 2 ) via twoelectron water oxidation reaction (2e-WOR) is an ideal process for delocalized production for water cleaning and other applications. Previously reported water oxidation catalysts have limited activity and selectivity, imposing a bottleneck for broad adaption of this technology. We identify ZnO as a new stable, non-toxic, active and selective catalyst for 2e-WOR to generate H 2 O 2 . Using density functional theory calculations, we propose that the (10 0) 1 facet of ZnO is an exceptional catalyst for 2e-WOR and confirm the prediction experimentally. We synthesize ZnO nanoparticles with a high fraction of (10 0) facets and find that this catalyst gives 1 an overpotential of 40 mV at 0.1 mA/cm 2 , and peak Faradaic efficiency of 81 % towards H 2 O 2 evolution.
