摘      要：In this work,a visible light photocatalyst based on Au modified BiVO_(4)microspheres was synthesized successfully through using a facile photodeposition method for visible light N_(2)fixation.Compared with pure BiVO_(4)microparticles(MPs),the obtained Au/BiVO_(4)MPs show superior N_(2)photofixation performance to BiVO_(4),owing to the enhancements of both the visible light absorption and charge carrier separation.After optimization,the actual NH_(4)^(+)generation rate of Au/BiVO_(4)reaches 0.419 mg·L^(-1),which is approximately 2 times higher than that of the pure BiVO_(4)one.The results presented herein provide new insights into rational design of highly active catalysts with Au NPs toward efficient,stable,and sustainable visible light N_(2)fixation in mild conditions.
