分别以聚乙二醇(PEG6000)及正硅酸乙酯(TEOS)为模板剂和硅源,采用沉淀法制备了 SiO2负载型磷钼酸(HPMo)催化剂 PEG-HPMo/SiO2,对催化剂进行了 FT-IR、XRD、FE-SEM 等表征。采用 NLDFT 平衡模型对吸附-脱附等温数据进行处理,计算了催化剂的孔径分布及比表面积。研究结果表明：催化剂 PEG-HPMo/SiO2含有HPMo 的 Keggin 结构且具有较高的脱硫活性。当催化剂用量0.06 g、H 2 O2用量0.04 mL、反应温度70℃、反应时间35 min 时,10 mL 模型油中的苯并噻吩(BT)基本被完全脱除；催化剂重复使用6次后,催化剂的催化活性没有明显降低。

PEG-HPMo/SiO2 catalysts were prepared through precipitation method using PEG6000 as template and tetraethyl orthosilicate (TEOS)as silica source.The catalysts were characterized by FT-IR,XRD and FE-SEM. Pore size distribution and specific surface area of catalysts were calculated through the NLDFT equilibrium model by using adsorption-desorption isotherm datas.Results showed that PEG-HPMo/SiO2 contained the Keggin structure as catalytic activity in HPMo.BT in 10 mL model oil can be totally removed under the conditions of catalyst 0.06 g, H 2 O2 0.04 mL,reaction temperature 70 ℃ and reaction time 35 min.The catalytic activity of PEG-HPMo/SiO2 is not significantly reduced after the catalysts was reused for 6 times.
