摘要
以钛酸四丁酯、氯化钬六水合物、无水乙醇为原料,采用简单的溶胶-凝胶法,成功制备出了Ho金属元素掺杂的Ho@TiO_(2)纳米光催化剂。采用XRD、FT-IR和PL等技术,对样品的晶体结构和性能进行表征,并优化了Ho@TiO_(2)纳米光催化剂配比,以玫瑰红B模拟废水进行探针反应,在可见光照射下评价其光催化性能。结果表明,与TiO_(2)纳米催化剂进行对比,Ho@TiO_(2)纳米光催化剂对玫瑰红B溶液(5 mg/L)表现出更高的可见光光催化降解性能,在可见光下照射180 min的脱色率达到95%。
Using tetrabutyl titanate,holmium chloride hexahydrate and anhydrous ethanol as raw materi⁃als,Ho metal doped Ho@TiO_(2) nano photocatalyst.The crystal structure and properties of the samples were characterized by XRD,FT-IR and PL techniques,and optimized Ho@TiO_(2).The photocatalytic activity of nano catalyst was evaluated under visible light by using rose red B simulated wastewater as probe reaction.The re⁃sults showed that Ho@TiO_(2) showed higher photocatalytic degradation performance of rose red B solution(5 mg/L)under visible light,and the decolorization rate reached 95%when exposed to visible light for 180 min.
