Water Oxidation to Hydrogen Peroxide Over a Super‐Aerophilic Graphite Catalyst
Advanced Materials, EarlyView.Design of super‐aerophilic graphite catalyst capable of trapping in situ produced oxygen gas on its surface under the electrolyte environment. By so doing, it is able to moderate intermediate species binding, which is critical to enabling the two‐electron water oxidation reaction to hydrogen peroxide.

Advanced Materials, EarlyView.We design and implement Au‐Cu co‐modified Zn3In2S6 catalyst with spatially decoupling charge carriers across bulk and surface sites, which effectively suppresses carrier recombination, drives surface hot electron accumulation and stabilizes intermediates for photocatalytic oxygen reduction. The optimized catalyst achieves an H2O2 evolution rate of 94.2
