N,O-coupling towards the selectively electrochemical production of H2O2
文献摘要：
Hydrogen peroxide(H2O2)synthesis generally involves the energy-intensive anthraquinone process.Al-ternatively,electrochemical synthesis provides a green,economical,and environmentally friendly route to prepare H2O2 via the two-electron oxygen reduction reaction,but this process requires efficient cata-lysts with high activity and selectivity simultaneously.Here,we report an N,O co-doped carbon xerogel-based electrocatalyst(NO-CX)prepared by a simple and economical method.The NO-CX catalyst exhibits a high H2O2 selectivity over 90％in a potential range of 0.2-0.6V and a high H2O2 production rate of 1410 mmol gcat-1 h-1.The density functional theory calculations demonstrate that the coupling effect be-tween N and O can effectively induce the redistribution of surface charge and the edge carbon atom adjacent to an ether group and a graphite nitrogen atom is the active site.This work provides a straight-forward and low-cost process to produce highly selective H2O2 catalysts,which is in place for the expan-sion of electrocatalytic synthesis of useful chemicals.
