摘　　要：Regulating the interaction between the substrate and electrode is crucial for maximizing catalytic performance.In this study,we developed a method for controlling the sintering temperature and introducing H2O2 post-treatment to modulate the N-doping of c catalysts,enhancing the interaction between the substrate and elec-trode to cause a radical reaction,thereby promoting electrocatalytic decarboxylation.When 10g of feedstock was used,the electrocatalytic system exhibited 9.4-and 4.2-fold increases in productivity and current efficiency,respectively,compared with the conventional method.A systematic investigation combining experiments and theoretical calculations revealed that pyridine N-oxide units not only promote bridging adsorption of the sub-strate and the formation of a substrate-enriched electric layer but also the transfer of mass and electrons,gen-erating more reactive carboxyl radicals.The electrocatalytic system delivers a current efficiency of 98%,which is exceptional compared to previously reported electrocatalysts.The system is in line with the development trend of the green chemical industry,combining flow reactors and photovoltaic technology.This study offers valuable insights and guidance for advancing electrocatalytic organic synthesis for future industrial applications.
