摘要

本研究采用水热法合成了WO3前驱体，通过调控退火温度得到系列WO3光电极，进一步在其表面负载CdZnS纳米颗粒后得到系列WO3/CdZnS异质结光电极，并研究了其对铜绿假单胞菌的灭活性能。研究发现，400°C退火的WO3与CdZnS复合后的WO3-400/CdZnS在光照40 min后对铜绿假单胞菌的灭活率可以达到100%。光电流密度变化曲线表明，WO3/CdZnS异质结的构建可以加速光生载流子的分离，因而具有更优的光催化灭菌性能。

Abstract

In this study, WO3 precursors were synthesized using the hydrothermal method. A series of WO3 photoelectrodes were obtained by adjusting the annealing temperature. After further loading CdZnS nanoparticles onto their surfaces, a series of WO3/CdZnS heterojunction photoelectrodes were prepared, and their inactivation performance against Pseudomonas aeruginosa was investigated. The study found that WO3-400/CdZnS, formed by combining WO3 annealed at 400°C with CdZnS, achieved a 100% inactivation rate against Pseudomonas aeruginosa after 40 minutes of illumination. The photocurrent density curves indicated that the construction of the WO3/CdZnS heterojunction accelerates the separation of photogenerated charge carriers, thereby exhibiting superior photocatalytic sterilization performance.
