Nanoporous BiVO₄/Bi₂S₃ nanosheets have been firstly fabricated through a two-step annealing followed by hydrothermal method using BiOI two-dimensional nanosheets as precursors, which could greatly improve the photoelectrochemical performances of BiVO₄ due to the enhanced charge separation efficiency and the enlarged absorption range. The optimal content of Bi₂S₃ in the BiVO₄/Bi₂S₃ nanocomposites has been explored by tuning the reaction time. In addition, it is found that loading co-catalysts FeOOH could further optimize the hole transfer pathway and thus enhance the photoelectrochemical water splitting ability.

纳米多孔BiVO ₄ / Bi ₂ S ₃纳米片的原位制备用于增强光电化学水分解

纳米多孔BiVO ₄ / Bi ₂ S ₃纳米片首先通过两步退火，然后以BiOI二维纳米片为前驱体进行水热法制备，由于电荷分离效率和电荷分离效率的提高，可以大大提高BiVO ₄的光电化学性能。扩大的吸收范围。BiVO ₄ / Bi ₂ S ₃中Bi ₂ S ₃的最佳含量已经通过调节反应时间探索了纳米复合材料。另外，发现负载助催化剂FeOOH可以进一步优化空穴转移途径，从而增强光电化学水分解能力。
