介孔TiO2的合成及其光催化性能的研究

Mesoporous TiO2 is a non-silicon transition metal oxide mesoporous material with high thermal stability and excellent photocatalytic property. In this dissertation, triethanolamine is used as template to synthesize mesoporous TiO2 in non-water systems. The prepared samples are characterized by XRD, UV-Vis, and N2 adsorption-desorption isotherm. All samples are mesoporous structure. The photocatalytic degradation experiments were carried out by using methyl orange (MO) as the target pollutant, the result shows that, the sample of TBOT:TEA:GCL = 1:1:20 has the best photocatalytic activity, as high as 67% after three hours.
