紫外光催化降解空气中甲醛的纳米二氧化钛复合涂料的研究

Study on Nano - Scale TiO2 Compound Coatings Causing Formaldehyde Degradation in Air under UV Catalysis

以硫酸钛、偏钛酸和硫酸氧钛浆料为原料,制备纳米二氧化钛,并用无机盐、酸等配制水性涂料,进行该涂料经紫外光催化降解空气中甲醛的研究试验。试验结果表明:这种低成本的纳米二氧化钛复合涂料可以有效地分解甲醛。

A waterborne coatings has been developed based on inorganic salts, acids and nano - scale TiO2, which was prepared with titanium sulfate, metatitanium acid, and titanyl sulfate. The test of the prepared coatings for formaldehyde degradation in air under UV catalysis has shown that this low cost nano - scale TiO2 compound coatings is effective for formaldehyde degradation.
