摘要
为了提高Ti O2的光催化活性,将不同种类的吸附剂与Ti O2混合使用,光催化分解水制氢。考察了各种吸附剂的添加量、牺牲剂的种类和浓度对光催化活性的影响。结果表明:牺牲剂醇溶液的浓度为30%时,产氢效果最佳。吸附剂的添加可有效提高光催化活性,在甲醇溶液中,活性炭、沸石和石墨硅的最佳添加量分别为50%、10%和50%时,光催化活性各增加2倍、8倍、25倍。
In order to improve the photocatalytic activity of TiO2 for water decomposition hydrogen, the different adsorbant were added to TiO2. The influence of the added amount of adsorbent, the kinds and concentration of alcohol solutions on the to photocatalytic activity were inspected. The results indicated that the optimal concentration of alcohol solution was 30 vol%. The addition of adsorbant can improve the photocatalytic activity of TiO2 effectively that the amount of hydrogen generation were increased to 2 times, 8 times and 25times when the added amount of active carbon, zeolite, graphite silica were 50 %, 10 % and 50 % respectively.
