以尿素、硝酸铜、钛酸四丁酯等为原料,采用溶胶-凝胶法,经Cu,N原子共掺杂制备出改性纳米TiO2光催化剂。采用 X射线衍射仪、扫描电子显微镜、紫外可见漫反射仪 、傅里叶变换红外光谱仪对其进行了分析表征。以甲苯气体为研究对象,考察了制备的TiO2光催化剂对甲苯的光催化降解性能。结果表明:共掺杂改性后的纳米TiO2光催化剂,在可见光400~550 nm处呈现出较强的吸收;当光催化反应120 min时,Cu-N-TiO2光催化剂对甲苯的催化降解转化率达到了38%,较纯纳米TiO2催化剂提高了近4倍。
- Abstract:
-
Using urea, cupric nitrate and tetrabutyl titanate as raw materials, the modified nano-TiO2 catalyst was prepared by sol-gel method through Cu and N atoms co-doping. The above prepared catalyst was characterized by X-ray diffraction, scanning electron microscopy, UV-vis diffuse reflectance and Fourier transform infrared spectrometer. Then taking toluene gas as the research object, the photocatalytic degradation of toluene by the modified TiO2 photocatalyst was investigated. The results showed that the co-doping modified nano-TiO2 photocatalyst had showed strong absorption in visible light region of 400-550 nm. When the photocatalytic reaction time was 120 min, the catalytic degradation conversion of Cu-N-TiO2 to toluene reached 38%, which was nearly 4 times higher than that of purenano-TiO2 .
