The results showed that (1) The grain size of nanometer YiO_2 was40～80nm.The wavelength corresponding to the maximum absorbency values were observedin the 200～320nm range.The crystal structure of carbon doped TiO_2 photocatalyst is primarilyanatase(22.43% rutile), and the content of carbon is about 4.6%.(2) The relative humidityvaring from 8% to 80%, the photocatalytic degradation degree of benzene increased withincreasing relative humidity; and to toluene, degradation rate was hanced by relative humidityup to 60%, and more or less inhibited above 60%.(3) Scheme and results of orthogonal testswere used by evaluating the photocatalytic performance of the gas phase methanol, acetoneand 1-heptane.The results revealed that their degradation degree reached 84.5%, 93.39% and93.45%, respectively.(4) The 254nm UV lamp showed higher photocatalytic degradation rate.For methanol, acetone and 1-heptane, it was found that photocatalytic degradation reactionoccurs with the light strength of daylight lamp.(5) Under the the same conditions, 15%degradation degree has been obtained for benzene, whilst about 10% degradation degree wasattained by Degussa P25; During the initial phases, the toluene revealed higher photocatalyticactivity, comparing with Degussa P25, the degradation degree of methanol, acetone and1-heptane were slightly lower.
