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.
