英文摘要	以SnCl2/SbCl3的乙二醇/乙腈混合液浸渍大孔SiO2载体，经多次水解沉积、高温煅烧制备大孔ATO/SiO2电极.SEM和XRD分析表明ATO（Sb-SnO2）微粒均匀负载在SiO2薄层上，4次水解沉积材料体积电阻率10 ?•cm，比表面77 m2•g-1.电化学测试表明，大孔ATO/SiO2电极在酸性条件下析氧电位2.5 V且对对氯苯酚的降解具有良好的电催化性能，而Fe2+的添加又可显著提高羟基自由基的产生率，从而进一步增大该电极的电流效率.; The macroporous ATO/SiO2 materials were prepared through multiple steps of hydrolysis deposition in ethylene glycol and acetonitrile mixed solutions of SnCl2/SbCl3 and subsequent calcination at high temperature. The structures of the obtained materials were characterized by means of SEM and XRD. The results showed that the nano-ATO chemically deposited on the SiO2 support underwent well-controlled aggregation and recrystallization to form a sandwich structure (ATO-SiO2-ATO). Through four times loading of ATO the volume resistivity and the specific surface area reached 10 ??cm and 77 m2?g-1, respectively. The oxygen evolution potential on macroporous ATO/SiO2 anode was 2.5 V in acidic condition and exhibited the electro-catalysis ability in degradation of 4-chlorophenol. It was also found that Fe2+ can significantly improve the current efficiency of ATO/SiO2 macroporous electrode in 4-chlorophenol solution by promoting the generation of OH radicals.; 973前期专项(No.2010CB635116)及宁波大学王宽诚基金资助; 作者联系地址：宁波大学，材料科学与化学工程学院，浙江宁波315211; Author's Address: Faculty of Material Science and Chemical Engineering , Ningbo University, Ningbo 315211, Zhejiang, China; 通讯作者E-mail：zhangruifeng@nbu.edu.cn
