摘　　要：基于金属离子掺杂技术,制备在可见光辐照条件下具有良好光催化性能的改性TiO2光催化防锈涂料,并研究其对甲醛气体的降解作用,利用X射线衍射和紫外-可见分光光谱表征改性TiO2光催化剂的微晶尺寸、晶体结构与光学性能。探讨了M/TiO2类型、光催化剂添加量、甲醛初始浓度、光源、涂膜层数和重复使用次数对甲醛降解的影响。结果表明:该光催化防锈涂料不仅具有良好的物理化学性能,还能达到净化室内空气的目的,在光催化剂掺杂量为2.5%,甲醛初始浓度为0.1μg/mL,涂膜层数为一层时效果最佳。Based on metal ion .doping technology, a modified TiO2 antirust coating was prepared, which boasting of better photocatalytic performance while visible light irradiation exists. The coating＇ s degradation property on HCHO gas was studied, and both X-ray diffraction and ultraviolet-visible diffuse reflection teehniques were used to characterize microerystal size, crystal structure and optical effect of the M/TiO2 photocatalyst. The influence of photocatalyst variety, the photoeatalyst＇ s additive amount , the formaldehyde＇ s initial con- centration, the lamps in indoor environment, the number of coatings and the repeated use times on the formaldehyde degradation were discussed to show that this photocatalytic antirust coating has excellent physical and chemical properties, and it can eliminate indoor air pollution, and the best effect can be achieved when the doping content of Cu-TiO2 stays at 2.5% together with 0. 1μg/mL initial concentration of formaldehyde and one coating layer.
