Abstract

Abstract Synthesis of H2O2 through oxygen electro‐reduction is a green sustainable route but suffers from the slow kinetics and limited cumulation of H2O2, because of the exceedingly slow oxygen diffusion and oxygen being directly reduced to water. Here, it has been proposed voltage pulse‐regulated catalysis achieves the continuous accumulation of H2O2 concentrations up to 50 times greater than constant catalysis based on the chain mail catalyst, which is capable of catalysis steadily for 3.6 million pulses (2000 h) at one current level. When using a flow cell, the preparation rate of 39 977 mmol gcat−1 h−1 is achieved, exceeding previous records. Because the applied voltage regulates the adsorption of O2/ H2O2 from the catalyst, as verified by molecular dynamics simulations, the chain mail catalyst exhibits a lower barrier to oxygen adsorption than the direct reduction of oxygen to water, achieving rapid and continuous cumulation. In addition, the direct use of in‐situ produced H2O2 achieves complete sterilization in two minutes demonstrating the potential for application at an industrial level.
