以钛酸正丁酯为前驱体制得钛凝胶涂覆在石英玻璃管上,通过热处理得到锐钛矿型纳米二氧化钛薄膜,并以此石英管为反应器,考察了纳米TiO2薄膜对NOx的光催化脱除能力,研究了涂膜次数、气体浓度、湿度对光催化效果的影响.结果表明经过120min的光催化反应,不同浓度的气体中NOx的脱除率均在95%以上.图5,参11.
Titanate titanate was used as a precursor to prepare a titanium gel coated on a quartz glass tube. Anatase-type nano-titanium dioxide film was obtained by heat treatment. Using this quartz tube as a reactor, The results show that after 120min photocatalytic reaction, the removal rates of NOx in different concentrations of gas are above 95% .Fig.5, Participation 11.
