摘要
半导体光催化氧化法是一种新兴的环境污染治理方法 ,具有非常广阔的应用前景。研究采用均匀沉淀法制备出环境净化新材料半导体材料光催化剂———纳米二氧化钛粉体 ,粒径 1 0nm ,晶型为锐钛矿型。着重介绍了利用光催化氧化的方法处理有机污染物苯酚溶液的试验条件 ,经紫外光照射后 ,苯酚的降解率达到 99.
The novel semiconductor photo-catalytic-oxidation process has been applied widely to decomposition of environmental pollutants. This paper introduces a high efficient photo-catalyst, nanosized titanium dioxide powder, prepared by uniform precipitation. The ultra-fine TiO 2 powder is a crystal of anatase with a particle size of 10nm. The treatment of phenol solution by photo-catalytic oxidation has also been carried out. When exposed to ultraviolet radiation, the phenol decomposition rate is above 99.9%.
