An investigation of Z-scheme homojunction BiVO4 photocatalysts for efficient green removal of ammonia nitrogen
Source abstract
Abstract
With in-depth research on photocatalytic pollution removal, homojunction semiconductors stand out for their simple structure and stability. However, their similar energy levels result in lower photocatalytic activity compared to heterojunctions, limiting their applications in photocatalysis. Therefore, in this study, homojunction BiVO 4 photocatalysts with staggered energy level structures were prepared by compositing crystalline facet-modified BiVO 4 with oxygen vacancy-modified BiVO 4 and used for the removal of ammonia nitrogen from water. The homojunction BiVO 4 photocatalysts were successfully prepared, and the good photocatalytic performance of OBVV-2 was confirmed by several characterizations and tests, with the ammonia nitrogen removal rate of 84.3 % under visible light, of which 93.6 % was converted into harmless N 2. The Z-scheme transfer mechanism was illustrated by radical capture experiments, and the repeated cycling experiments demonstrated that the homojunction photocatalysts have excellent stability. In conclusion, this study confirmed that the Z-scheme homojunction BiVO 4 (OBVV-2) photocatalyst has good potential for application and provides a homojunction solution for efficient and green ammonia nitrogen removal.
