Abstract:Mesoporous Ti-HMS is able to be used as an active "single-site" photocatalyst for the gas-phase heterogeneous degradation of benzene, a notorious aromatic organic pollutant. In particular, it has been found that Ti-HMS shows enhanced activity and stability toward degradation of benzene as compared with commercial mania (Degussa, P25), which could be attributed to its unique features of large surface area, highly dispersion state of Ti oxide species and mesoporous channel structure This suggests that there is a promising potential in using Ti-containing molecular sieves as a photocatalyst for degradation of volatile aromatic organic pollutants in air, therefore advancing the applications of such "single-site" photocatalyst in environment cleanup.
