摘      要：Electrosynthesis of hydrogen peroxide(H2O2)is an on-site method that enables independent distribution applications in many fields due to its small-scale and sustainable *** crucial point remains developing highly active,selective and cost-effective *** electrosynthesis of H2O2 in acidic media is more practical owing to its stability and no need for further *** herein report a phosphorus and selenium tuning Co-based non-precious catalyst(CoPSe)toward two-electron oxygen reduction reaction(2e–ORR)to produce H2O2 in acidic *** starting point of using both P and Se is finding a balance between strong ORR activity of CoSe and weak activity of *** results demonstrated that the CoPSe catalyst exhibited the optimized 2e–ORR activity compared with CoP and *** disclosed an onset potential of 0.68 V and the H2O2 selectivity 76%-85%in a wide potential range(0–0.5 V).Notably,the CoPSe catalyst overcomes a significant challenge of a narrow-range selectivity for transitionmetal based 2e–ORR ***,combining with electro-Fenton reaction,an on-site system was constructed for efficient degradation of organic *** work provides a promising non-precious Co-based electrocatalyst for the electrosynthesis of H2O2 in acidic media.
