Abstract Cu2FeSnS4 (CFTS) particles were synthesized via a simple and versatile solvothermal route. The material was employed as a catalyst for the degradation of tartrazine dye from aqueous solution through the solar photo-Fenton process, reaching 95% of dye degradation at 50 min of reaction time. Powders containing a mesoporous structure with high surface area and total pore volume were obtained. The catalyst showed high chemical stability and degradation efficiency of tartrazine dye after five recycles. Therefore, CFTS shows intrinsic characteristics for potential application as a solar photo-Fenton catalyst in the tartrazine degradation from aqueous solution.

溶剂热法制备的Cu 2 FeSnS 4 颗粒作为太阳能光芬顿催化剂的新应用

摘要 Cu2FeSnS4 (CFTS) 颗粒是通过一种简单而通用的溶剂热途径合成的。该材料被用作通过太阳能光-芬顿法从水溶液中降解柠檬黄染料的催化剂，在反应时间为 50 分钟时达到 95% 的染料降解。获得了包含具有高表面积和总孔体积的介孔结构的粉末。该催化剂在五次循环后对柠檬黄染料表现出较高的化学稳定性和降解效率。因此，CFTS 显示出潜在应用的内在特性，作为太阳能光芬顿催化剂在水溶液中降解柠檬黄。
