摘　　要：以钛酸丁酯为主要原料,利用溶胶-凝胶法制备了纳米TiO2,Co/TiO2粉体。掺杂钴能够延缓TiO2由锐钛矿相向金红石相转变,从而提高纳米Co/TiO2粉体的催化活性。经500℃焙烧的纳米Co/TiO2粉体,在紫外光源下能有效催化直接溴酚兰染料降解。TiO2 and Co/TiO2 nanoparticles were prepared from butyl titanate by sol-gel method.Co was adulterated in TiO2 to slower conversion of TiO2 from anatase into rutile and improve photocatalytic activity of Co/TiO2 nanoparticles.The Co/TiO2 nanoparticles of calcination at 500 ℃ exhibited photocatalytic degradation activity to direct bromophenol blue under xenon lamp.
