Abstract

FeSe-WSe2 composite photocatalyst was synthesized by a facile one-pot hydrothermal reaction with WSe2, sodium selenite (Na2SeO3), hydrazine hydrate (N2H4and#183;H2O), hydrochloric acid (HCl), and Ferric chloride (FeCl3). Different ratios of FeSe-WSe2 composite photocatalysts were synthesized according to different Fe content, and FeSe-WSe2 was characterized by XRD, SEM, UV-vis DRS and XPS. At the same time, the photocatalytic performance and catalytic mechanism of the composite photocatalyst were explored through the degradation of methylene blue (MB) by the composite. The experimental results show that under the best experimental conditions, the 37at% (Atomic ratio) FeSe-WSe2 composite has the best removal effect on MB solution, and the removal rate reaches 99.8%. This shows that there is a synergistic effect of photocatalysis and Fenton reaction, which greatly improves the degradation ability of pollutants of FeSe-WSe2. Since the degradation of pollutants by photo Fenton is carried out under neutral conditions, it is more conducive to future applications in actual production.

一锅法制备FeSe-WSe2复合材料及其光Fenton降解亚甲基蓝的性能

以WSe2、亚硒酸钠（Na2SeO3）、水合肼（n2h4和#183；H2O）、盐酸（HCl）和三氯化铁（FeCl3）为原料，采用一锅水热反应制备了FeSe-WSe2复合光催化剂。根据不同的Fe含量合成了不同配比的FeSe-WSe2复合光催化剂，并通过XRD、SEM、UV-vis DRS和XPS对FeSe-WSe2进行了表征。同时，通过复合材料对亚甲基蓝（MB）的降解，探索复合光催化剂的光催化性能和催化机理。实验结果表明，在最佳实验条件下，37at%（原子比）FeSe-WSe2复合材料对MB溶液的去除效果最好，去除率达到99.8%。这说明光催化与Fenton反应存在协同作用，大大提高了FeSe-WSe2对污染物的降解能力。由于光芬顿对污染物的降解是在中性条件下进行的，因此更有利于未来在实际生产中的应用。
