Abstract

In the research, the Cadmium selenide /bismuth molybdate (CdSe/ Bi₂MoO₆) nanocomposite was successfully prepared using a hydrothermal method and characterized. The effect of irradiation time, pH, initial RY145 concentration, and nanocomposite dosage on the removal performance of RY145 was investigated, and the results revealed that CdSe/Bi₂MoO₆ nanocomposite improved the photocatalytic degradation of reactive yellow 145(RY145) until 86% in the following conditions: [RY 145]0 = 20 mg/L, nanocomposite dosage = 200 mg/L, pH = 2; Vis. Light = 300 W; time = 60 min. Also, it was found that hydroxyl radicals (°OH) are the major scavenging agent in RY145 degradation and CdSe/Bi₂MoO₆ nanocomposite has excellent stability after 5 cycles. Ultimately, the CdSe/Bi₂MoO₆ nanocomposite can be used as a novel nanocomposite with a high potential for removing RY145 from aqueous solutions.

硒化镉/钼酸铋纳米复合材料光催化降解活性黄145染料。

本研究采用水热法制备了硒化镉/钼酸铋（CdSe/ Bi2MoO6）纳米复合材料，并对其进行了表征。结果表明：CdSe/Bi2MoO6纳米复合材料在[RY 145]0 = 20 mg/L，纳米复合材料投加量= 200 mg/L, pH = 2的条件下，对活性黄145（RY145）的光催化降解率达到86%；可见光= 300 W；时间= 60分钟。此外，还发现羟基自由基（°OH）是RY145降解的主要清除剂，CdSe/Bi2MoO6纳米复合材料在5次循环后具有优异的稳定性。最终，CdSe/Bi2MoO6纳米复合材料可以作为一种新型纳米复合材料，具有从水溶液中去除RY145的高潜力。

期刊介绍： BMC Chemistry, formerly known as Chemistry Central Journal, is now part of the BMC series journals family. Chemistry Central Journal has served the chemistry community as a trusted open access resource for more than 10 years – and we are delighted to announce the next step on its journey. In January 2019 the journal has been renamed BMC Chemistry and now strengthens the BMC series footprint in the physical sciences by publishing quality articles and by pushing the boundaries of open chemistry.
