“…Metal oxides still deliver other charming properties include but are not limited to low toxicity, easy to be synthetic and excellent environment stability, having been emerged as promising catalysts in water splitting, nitrogen fixation, and ORR. [ 8 ] Previous studies have shown that metal oxides suffer from poor activity or low selectivity when employed as ORR catalysts, which heavily hinder the applications of metal oxides in the field of 2e − ORR. [ 9 ] Moreover, the research of metal oxides for ORR mainly focuses on transition metal oxides, while the research on main group metal oxides is rarely reported.…”

Direct electrosynthesis of hydrogen peroxide (H2O2) via two‐electron pathway oxygen reduction reaction (2e− ORR) is crucially essential for a sustainable green economy. However, catalysts inevitably undergo four‐electron pathway oxygen reduction reaction (4e− ORR), resulting in low selectivity and economic benefits. The current challenge is to provide a feasible design strategy for obtaining satisfactory 2e− ORR catalysts with high selectivity. In this work, carbon dots (CDs) act as a cocatalyst to regulate the electron transport kinetics of In2O3/CDs, and the influence of CDs on the ORR pathways of In2O3/CDs is also studied. The electron transfer kinetics on In2O3/CDs composites are studied and analyzed using the transient photo‐induced voltage (TPV) technology. Combining the TPV results and kinetics analysis, it is shown that the electron transport on the In2O3 interface is obviously weakened after the addition of CDs, resulting in a high H2O2 selectivity. It is also demonstrated that CDs can effectively enhance the selectivity of H2O2, and the H2O2 selectivity of In2O3/CDs–10 is in close proximity to 100%, which is much higher than that of pure In2O3 (72%). This work will provide a new understanding and insight into addressing the challenge of low H2O2 selectivity for 2e− ORR catalysts.
