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.

Bi ₂ Te ₃片有助于形成花状BiOCl复合材料并增强N _2的光固定能力

N _2光固定被认为是一种绿色环保的氨合成方法。在这项工作中，Bi ₂ Te ₃用于修饰BiOCl以形成高活性的复合微花状结构光催化剂。在紫外光照射下，Bi ₂ Te ₃ / BiOCl的有效氨释放速率达到315.9μmol/ L·h 。根据两个组分的带隙和还原电势分析，BiOCl产生的电子归因于N ₂光固定，而Bi ₂ Te ₃激发产生的光生电荷有效地抑制了BiOCl的光生空穴电子的复合。
