TiO₂纳米棒光催化降解甲基橙的研究

摘要: 本文以甲基橙为目标降解物考察了催化剂的添加量、甲基橙溶液的pH值、晶化时间、热处理温度等因素对用“软模板”制备的TiO₂纳米棒光催化活性的影响。研究表明:当催化剂添加量为0.08g、甲基橙溶液的pH=4、晶化时间为24h、热处理温度为500℃时,TiO₂光催化剂的催化效果最佳,达到了85.96%。

Abstract: In this paper,with the methyl orange as degradation object,the effect of the addition of catalyst,methyl orange solution pH,reaction time,heat treatment,acid unequal on the catalytic activity of TiO₂ nanorod was investigated.The results show that when the catalyst dosage is 0.08g,methyl orange solution pH is 4,the crystallization time is 24h and the heat treatment temperature is 500 ℃,catalytic effect of TiO₂ photocatalyst reaches maximum that is 85.96%.
