摘要:

光催化还原是处理水溶液体系中六价铬(Cr(VI))的一种新方法. 层状铋(Bi)基材料具有增强的光捕获能力和可调的带隙能量, 被认为是一种光催化还原去除Cr(VI)的有效材料. 本文从修饰策略(如异质结、缺陷工程和掺杂)和工艺变量(如溶液pH和添加剂的类型/数量)等方面, 对用于光催化还原处理Cr(VI)的铋基材料的改进机制进行深入总结. 此外, 采用工业上用作关键指标的优值系数(FoM), 对各种铋基材料的性能进行评估. 结果发现, 平均粒径为5‒10 nm, 具有shuriken形状的BiVO4具有最高的FoM值(3.45×10-5 mol g-1 Wh-1), 且其光催化还原性能最好. 同时, 与其他非铋基催化剂相比, BiVO4的光催化还原Cr(VI)性能也具有很好的优势. 但是, 目前铋基催化剂成本较高, 且光催化还原过程能耗较大, 距离大规模实际应用还有一定的距离. 未来, 为实现铋基催化剂光催化还原处理含Cr(VI)废水的大规模应用, 应大幅度降低催化剂的生产成本, 并提高催化剂光子吸收效率从而进一步提高能源利用率.

Abstract:

abstract: Photocatalytic reduction (PCR) is an emerging option to treat hexavalent chromium (Cr(VI)) in aquatic systems. The lamellar bismuth (Bi)-based materials are recognized as a potential platform for PCR against Cr(VI) with enhanced light harvesting ability and tunable bandgap energy. The PCR mechanism of Bi-based materials against Cr(VI) has been explored in relation to the modification strategies (e.g., heterojunction, defect engineering, and doping) and to the process variables (e.g., solution pH and the type/quantity of additives). Performance evaluation of diverse Bi-based materials has also been made using a figure of merit (FoM) as the key metric for industrially relevant conditions. Accordingly, shuriken-shaped BiVO4 with average particle sizes of 5‒10 nm was recognized as the best performer with the highest FoM value (3.45 × 10-5 mol g-1 Wh-1). To scale up the utility of Bi-based materials against Cr(VI), further efforts should be directed toward drastic reduction of treatment costs for real-world applications, especially in terms of catalyst fabrication and energy consumption (due to poor quantum yield).
