纳米TiO2/聚糠醛复合物涂布纸的光催化性能

摘要

With acid catalyst, furfural was polymerized on the surface of nano TiO2. The photocatalytic decomposition of formaldehyde with nano TiO2 and nano TiO2/furfural coated papers were studied respectively. The results showed that the photocatalytic decomposition efficiency of nano-TiO2/furfural polymer composite coated paper has been improved greatly compared with that paper coated with pure TiO2. Especially in natural light conditions, the improvement of photocatalytic efficiency was more prominent.%在一定酸催化条件下,将糠醛聚合于纳米TiO2表面,分别对基于纳米TiO2和纳米TiO2/聚糠醛复合物的涂布纸进行甲醛的光催化分解去除研究.结果表明,涂覆TiO2/聚糠醛复合物纸样的光催化分解效率比单纯TiO2有较大程度提高,尤其是在自然光照射条件下,光催化效率提高更明显.
