摘　　要：以钨酸钠为钨源、草酸做辅助剂、钛酸四丁酯为钛源,采用原位水解的方法制备了三氧化钨/二氧化钛的复合材料。通过X-射线衍射(XRD)、扫描电镜(SEM)和透射电镜(TEM)对制备样品的晶体结构、尺寸、形貌等进行了测试表征,并利用光催化反应装置和WS-30A气敏测试系统对产物光催化性能及气敏性能进行了表征。结果表明:三氧化钨/二氧化钛复合材料的光催化性能以及气敏性能较纯WO_(3)都有明显的提高。WO_(3)/TiO_(2) composites were prepared by the methods of in situ hydrolysis using sodium tungstate as tungsten source,oxalic acid as auxiliary and tetrabutyl titanate as the precursor.The shape and structure of the product were characterized by XRD,SEM and TEM.The performance of the photocatalytic properties and gas sensing for samples were characterized by photocatalytic reaction apparatus and gas sensing measurements WS-30A.The results indicated that the photocatalytic performance and gas sensing properties of the composites were significantly improved compared with WO_(3).
