Abstract
The N2 photofixation has been considered as a green and eco-friendly ammonia synthesis approach. In this work, Bi2Te3 was employed to modify BiOCl for the formation of a highly active composited micro flower-like structure photocatalyst. Efficient ammonia evolution rate reached 315.9 μmol/L·h over Bi2Te3/BiOCl under UV light irradiation. Based on the analysis of bandgap and reduction potential of two components, the electrons generated from BiOCl is attributed to the N2 photofixation, while the photogenerated charges from the excitation of Bi2Te3 suppress the recombination of photogenerated hole-electron of BiOCl effectively.
