主 题：Photocatalysis Electron transfer Fe atom embedded N-doped graphene oxide Ta_(3)N_(5) Catalysis
摘 要：Energy crises and environmental pollution have become urgent problems with human civilization *** technology is a green method to deal with these *** key to improve photocatalytic efficiency lies in the effective separation of photogenerated electron-hole *** this work,we designed the Fe atom embedded N-doped graphene oxide(Fe-NGO)supporting on tantalum nitride(Ta_(3)N_(5))catalyst,which was employed to improve the photocatalytic oxygen production *** oxygen production of 5 wt%Fe atom embedded N-doped graphene oxide supporting on tantalum nitride(Fe-NGO/Ta_(3)N_(5))was 184.7μmol·g^(-1),about 3.5 times higher than that of the pure Ta_(3)N_(5).The introduction of the cocatalyst Fe-NGO acting as an electron conductor in the Fe-NGO/Ta_(3)N_(5) accelerates the carrier migration of Ta_(3)N_(5) and further enhances the photocatalytic oxygen production activity.N-doping increases the conductivity of graphene oxide(GO),and Fe atoms are used as the reactive sites to promote the combination of electron and sacrificial agent in the *** work may provide insights into the research of new carbon.
