【摘要】 本文以纳米颗粒TiO2 为活性组分 ,制备了不同的负载化催化剂 ,并对三氯乙烯 (TCE)气相光催化氧化过程进行了研究。实验结果表明在近紫外光的照射下 ,气相污染物可被迅速降解。载体不仅起到固定活性组分的作用 ,而且其吸附作用有助于更好地发挥活性组分的催化活性。更多还原

【Abstract】 The gas photocatalytic oxidation of TCE has been studied and various supported catalysts has been prepared by titanium dioxide nm-particles as active constituent.The experiment has shown that gas pollution can be decomposed quickly under ultraviolet light.The carrier has been used to fix active constituent and further,the adsorption function of it contributc to catalytic activity of active constituent.更多还原
