摘要：
Visible-light photocatalysis composite adsorption material was prepared by combining activated carbon and nitrogen-doped TiO2 by impregnation method. The study results show that the droped nitrogen in TiO2 has improved the visible-light absorption activity, the activated carbon adsorption is a plausible method for the removal of formaldehyde in the air, the loading of nitrogen-doped TiO2 on activated carbon has trifling effect to adsorption process in low concentration of volatile organic compounds (VOCs) condition and nitrogen-doped TiO2-activated carbon material has excellent visible-light photocatalytic activity. The results show that this kind of material splits absorption and photocatalysis apart and improve the re-use performance of activated carbon.
