2Enhanced photocatalytic ammonia oxidation activity and nitrogen selectivity over Ag/AgCl/N-TiO_(2) photocatalyst显示文摘The removal of ammonia(NH_(3))emitted from agricultural and industrial activities is of great significance to protect human health and ecological environment.Photocatalytic NH_(3)oxidation to N2under mild conditions is a promising strategy.However,developing visible light photocatalysts for NH_(3)oxidation is still in its infancy.Here,we fabricate N-TiO_(2)and Ag/AgCl/N-TiO_(2)photocatalysts by sol-gel and photodeposition methods,respectively.The introduction of N not only endows TiO_(2)with visible light response(absorption edge at460 nm)but also results in the formation of heterophase junction(anatase and rutile).Thus,N-TiO_(2)shows 2.0 and 1.8 times higher than those over anatase TiO_(2)and commercial TiO_(2)for NH_(3)oxidation under full spectrum irradiation.Meanwhile,surface modification of Ag can simultaneously enhance visible light absorption(generating localized surface plasmon resonance effect)and charge separation efficiency.Therefore,the photocatalytic activity of Ag/AgCl/N-TiO_(2)is further improved.Furthermore,the presence of N and Ag also enhances the selectivity of N2product owing to the change of reaction pathway.This work simultaneously regulates photocatalytic conversion efficiency and product selectivity,providing some guidance for developing highly efficient photocatalysts for NH_(3)elimination.Jiaojiao Guan Daorong Li Jiahui Feng Peng Xu Zhaonian Li Siqi Ge Hongxia Chen Kunfeng Zhang 2024Journal of Environmental Sciences2024,,4:0
