摘　　要：With the ever-growing demand of clean water for the healthy world,water purification has become an urgent global issue.Singlet oxygen(^(1)O_(2))as unique non-radical derivative of oxygen,possessing unoccupiedπ*orbital and exhibiting high selectivity towards electron-rich organic pollutants.Nevertheless,most of the approaches suffer from low-efficiency or biotoxicity,which severely restrict their potential applications.Therefore,in this work,we propose a general strategy via photoelectrocatalytic for selectively reducing oxygen to^(1)O_(2)with designed carbon bridged carbon nitride(CBCN).This work highlights the important role of synergistic photo-electro-catalytic effect for selectively generating the^(1)O_(2)via oxygen reduction pathway,which can be a promising way especially for degrading electron-rich pollutants.
