چکیده انگلیسی
In the present work, Ti-beta was prepared through the gas-solid reaction of beta with vapor TiCl4, and characterized by means of XRD, FT-IR and UV-vis diffuse reflectance. Titanium atoms have been incorporated into the framework of beta, and no TiO2 species was detected in Ti-beta. The photocatalytic activity of hydrogen evolution by UV-photocatalytic decomposition of methanol gas over Ti-beta was examined in a continues-flow quartz reactor at room temperature. The amount of hydrogen evolution per Ti-ion surface on Ti-beta is much higher than that of TiO2 and TiO2/beta. The titanium atoms incorporate into the framework of beta are the photocatalytic active centers.
