Preparation and Cataly tic Degradation of Acid Orange 7 in the Dark on Cu2O@Cu4(SO4)(OH)6

  • 摘要: 本文采用液相还原法合成出具有不同摩尔比的Cu2O/Ag(x)复合型催化剂,采用XRD、SEM、UV-Vis-NIR漫反射(DRS)分析手段对样品进行表征。结果显示,纳米金属Ag的存在,使得Cu2O/Ag(x)样品对光的吸收扩展到了整个可见和近红外区,且随样品中Ag含量的增加,该区域的吸收逐渐增强,证明Cu2O/Ag(x)复合催化剂对太阳光具有高的光吸收能力。以甲基橙(MO)为目标降解物,研究催化剂在黑暗条件下的降解性能,结果表明Cu2O/Ag(0.05)催化剂具有最高的降解能力,在120 min内黑暗条件下MO (30 mg?L-1) 降解率达到89.2%。同时对Cu2O/Ag(x)复合催化剂的降解机理进行了探讨。
