| Abstract: | TiO_2 was used as a photocatalyst and activated carbon fibres that supported TiO_2 as an adsorbent to decontaminate formaldehyde gas of low concentration.The photocatalyst was prepared by sol-gel technique and modified with Fe~(3 )and so it got a higher activity. Activated carbon fibres loaded with TiO_2 was exposed to UV light with the result that formaldehyde gas was adsorbed by ACF and then photocatalytic oxidized into CO_2 and H_2O. In the experiment, effects of reaction time, does of titanium dioxide and formaldehyde concentration have been studied, and the adsorption capability of ACF used in photocatalytic oxidation was also tested. |
