Synthesis of Carbon-doped Mesoporous TiO2 Visible-light Photocatalytic Materials via One Pot Solvothermal Method
摘要
Abstract
C doped TiO2 mesoporous materials with spherical morphology were synthesized via solvothermal method in ethanol, using tetrabutyl titanate( TBOT) as the titanium source under template-free condition. The synthesized samples were characterized by XRD, SEM, TEM, N2 adsorption-desorption, XPS, UV-Vis, and photocatalytic degradation of RhB. The results indicated that, the synthesized samples were pure phase anatase TiO2 , and they had morphology of uniform size spheres with the accumulation of the nanoparticles. The crystallinity and morphology of the synthesized samples could be regulated by the volume of adding acetic acid during the synthesis process. The results showed trace of C atoms getting into TiO2 crystal lattice, replacing the position of O atoms, narrowing the band gap of TiO2 , and leading to the enhancement of visible light absorption. Photocatalytic test confirmed its excellent adsorption property and photocatalytic activity under visible light, which have very important meaning for solving environmental problems in current society.关键词
