环境条件对氟、氮共掺杂TiO2光催化降解甲醛活性的影响
Effect of Ambient Conductions on Degradation of Formaldehyde by F and N Co-Doped TiO2 Photocatalyst
【摘要】 以F-N-TiO2为光催化剂,以蓝色发光二极管为光源,考察了环境温度、湿度和光照强度对降解甲醛的影响。结果表明环境条件对可见光下催化剂F-N-TiO2降解甲醛有较大影响,最佳环境条件为:温度40℃、湿度50%,发光二极管光照强度适当增大也有利于提高光催化降解甲醛活性。
【Abstract】 Using F-N-TiO2 as photocatalyst and LED as the light source,the effects of ambient temperature,relative humidity and light intensity on the degradation of formaldehyde have been investigated.The results show that the ambient conductions have considerable influence on the degradation of formaldehyde by F-N-TiO2 under visible light irradiation.The optima ambient conditions for temperature and relative humidity are 40 ℃ and 50% respectively.The increase of LED light intensity is beneficial to the activity of photocatalytic degradation of formaldehyde.
