With the ever-growing demand of clean water for the healthy world,water purification has become an urgent global issue.Singlet oxygen (1O2) as unique non-radical derivative of oxygen,possessing unoc-cupied π* 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 selec-tively reducing oxygen to 1O2 with designed carbon bridged carbon nitride (CBCN).This work highlights the important role of synergistic photo-electro-catalytic effect for selectively generating the 1O2 via oxy-gen reduction pathway,which can be a promising way especially for degrading electron-rich pollutants.
