pH值及含水量对自蔓燃制备TiO2光催化性能的影响
Effects of pH Value and Water Content on Photocatalytic Activity of TiO2 Prepared with Sol-Gel Auto-igniting Synthesis Method
摘要
Abstract
In order to investigate the effects of pH value and water content on the photocatalytic activity of TiO2 prepared by sol-gel auto-igniting synthesis (SAS) method, TiO2 powders wereprepared by changing pH value and water content, while using TiO (NO3) 2 prepared by the TiCl4 as precursor, and fixing the ratio of n(TiCl4): n(C6H8O7): n(NH4NO3)=1:1: 3, the sintering temperature was 550 ℃. The results showed that the photodegradation rates constant gave the highest values with TiO2 powders prepared with pH value of 7 and water mass fraction of 50％. The powders showed as excellent loose and porous materials.关键词
