Abstract

This study presents a Bi₁₂O₁₅Cl₆/Bi₂WO₆ (CW) heterojunction photocatalyst prepared by solvothermal method combined with calcination. The structural, surface morphological and spectral properties of samples were analyzed using XRD, SEM, XPS, BET, UV–Vis DRS and PL spectroscopy. The photocatalytic degradation efficiency towards RhB is up to 94.4 % under visible-light irradiation for 60 min. Free radical trapping experiments revealed h⁺ was the key active species for photodegradation. The photoluminescence spectroscopy and the transient photocurrent responses demonstrated that the enhanced photocatalytic activity mainly originates from the separation of photogenerated electron-hole pairs. This study not only provides a photocatalyst-design strategy, but also contributes to the pollutant treatment field.

制备具有高效光催化降解罗丹明B性能的Bi12O15Cl6/Bi2WO6异质结光催化剂

采用溶剂热法结合煅烧法制备了Bi12O15Cl6/Bi2WO6 （CW）异质结光催化剂。采用XRD、SEM、XPS、BET、UV-Vis DRS和PL光谱分析了样品的结构、表面形貌和光谱性质。在可见光照射60 min的条件下，对RhB的光催化降解效率可达94.4%。自由基捕获实验表明h+是光降解的关键活性物质。光致发光光谱和瞬态光电流响应表明，光催化活性的增强主要来自于光生电子-空穴对的分离。该研究不仅提供了一种光催化剂设计策略，而且对污染物处理领域具有重要意义。
