Ex Situ and In Situ Analyses of the Mechanism of Electrocatalytic Hydrogen Peroxide Production by CoxZn1–xO (0 < x < 0.018) Materials in Alkaline Media
Abstract:Metal oxide semiconductors have attracted
much attention due to
their versatility in different applications, ranging from biosensing
to green energy-harvesting technologies. Among these metal oxides,
oxide-based diluted magnetic semiconductors have also been proposed
for fuel cell applications, especially for the oxygen reduction reaction
(ORR) and the oxygen evolution reaction. However, the catalytic mechanism
has been proposed to follow a two-electron pathway, forming hydrogen
peroxide, instead of the four-e… Show more
