主　　题：Catalyst Solar energy Hydrothermal BiO_(2-x)/NaNbO_(3) Photocatalytic N_(2)-fixation 

摘      要：The fabrication of heterojunction catalysts is an effective strategy to enhance charge separation efficiency,thereby boosting the performance of *** this study,BiO_(2-x)nanosheets were synthesized through a hydrothermal process and loaded onto NaNbO_(3) microcube to construct a series of BiO_(2-x)/NaNbO_(3) heterojunctions for photocatalytic N_(2) *** indicated that 2.5%BiO_(2-x)/NaNbO_(3) had the highest photocatalytic *** NH_(3) production rate under simulated solar light reached 406.4μmol·L^(-1)·g^(-1)·h^(-1),which reaches 2.6 and 3.8 times that of NaNbO_(3) and BiO_(2-x),***_(2-x)nanosheets primarily act as electron trappers to enhance the separation efficiency of charge *** strong interaction between BiO_(2-x)and NaNbO_(3) facilitates the electron migration between ***,the abundant oxygen vacancies in BiO_(2-x)nanosheets may facilitate the adsorption and activation of N_(2),which may be another possible reason of the high photocatalytic activity of the BiO_(2-x)/NaNbO_(3).This study may offer new insights for the development of semiconductor materials in photocatalytic nitrogen fixation.
