纳米TiO2的合成与光催化性能
Synthesis of nano-TiO2 and its photocatalytic properties
摘要
Abstract
Nano-TiO2 was synthesized via solid state reaction coupled with calcination or diluted acid treatment method respectively. The catalytic properties were investigated. The results show that the crystal phase is controlled by alkali quantity. The anatase titania was obtained at low OH-/Ti+4 ratio and the mixture between anatase and brookite was shown at high OH-/Ti+4 ratio. The phase transformation was controlled by nitric acid. The loading of silver results in the decrease of specific surface area. While the interaction between the titania and silver can inhibit the sintering of titania during the calcination process and decrease the reduction temperature of titania. Thus, the photocatalysis activity is dramatically increased.关键词
