溶胶-凝胶法制备共掺杂负载型二氧化钛光催化剂
Preparation on Photocatalysis Activities of Co Doping TiO2 by Sol Gel Method
摘要
Abstract
Takingtetrabutyl titanate as Ti source,this paper synthesizes the'different metal-N'codoped TiO2 nano powder by sol-gel method,and compares the effects of alcohol’amount on phthalic acid ester hydrolysis.The photocatalytic activity and size of doped TiO2 powder are characterized by ultraviolet-visi-ble absorption spectroscopy (UV-Vis)and X-ray diffraction (XRD).The result shows that the gel time in turn increases with the increase of tetrabutyl titanate butyl and anhydrous ethanol volume ratio.The single metal doped light catalyst activity is stronger than that of various metals.Compared with Mn2+,Cu2+, Fe3+,Al3+,Ba2+,CO2+ and Fe3+,the CO2+ and N-Co doped TiO2 powder is the most active under condi-tion of visible�light.关键词
