Synthesis and Paclobutrazol Visible-light Degradation of Al/S Doped TiO2 Mesoporous Materials with Pyridine as a Template

摘要：

　　Al and S co-doped TiO2 (S-Al-TiO2) mesoporous materials as a kind of visible light photocatalysts are prepared using pyridine as a template through a solid state reaction route.The materials features are characterized by the advanced instruments.The photodegradation kinetic of paclobutrazol is investigated.It is shown that the doping of S and Al could effectively inhibit the growth of anatase TiO2,both S and Al have entered into the lattice of TiO2.Surface area of 81.3m2/g and narrow pore size distribution (~2.1nm) are presented,it not only enables the visible-light absorption but also promotes photocatalytic property of paclobutrazol.Moreover,within 150 min of visible-light irradiation,the photocatalytic degradation of paclobutrazol approximately follows an order kinetics,and the photodegradation rate in 46.7% and reaction rate constant of 0.00414 min-1 are obtained.
