摘要

利用光化学合成法制备了SnO2光催化材料。通过X射线衍射(XRD)、扫描电镜(SEM)等手段对材料进行表征。研究了该材料对Pb(Ⅱ)光催化还原性能。结果表明:SnO2对Pb(Ⅱ)表现出良好的光催化还原性能。催化动力学研究发现在有机酸和Pb(Ⅱ)的混合体系里,乙酸-Pb(Ⅱ)表现出最大的表观速率常数,体现了较强的协同作用。

Abstract

SnO2 was synthesized by a photochemical synthesis method and characterized by XRD and SEM.The photocatalytic tests showed that SnO2 had good photocatalytic activity in the reduction of aqueous Pb(Ⅱ) under ultraviolet light irradiation.The catalytic kinetics study found that acetic acid-Pb(Ⅱ) showed the largest apparent rate constant in the mixed system of organic acids and Pb(Ⅱ),which reflected a stronger synergy.
