| 摘 要： | 以商品TiO2-P25为原料,通过浸渍法负载一定量过渡金属Cu,得到一系列不同含量的CuOx/TiO2光催化剂.利用X射线衍射(XRD),X-射线光电子能谱(XPS),BET,高分辨率透射镜(HRTEM),X射线荧光光谱(XRF)和光致发光光谱(PL)等方法对催化剂进行了详细表征,在自建的光催化反应器中评价了气态水光催化还原CO2反应的活性和CH4收率.结果表明负载CuOx后的TiO2纳米材料光催化性能显著提高,其中1%CuOx/TiO2样品紫外光照72 h后,CH4生成量达到了24.86μmol.gTi-1.同时,CuOx负载量、反应温度、反应时间等因素对CH4收率均有显著影响.

| Abstract: | Using TiO2-P25 as a main material,CuOx loaded TiO2-P25 photocatalysts were prepared via wet impregnation method.The catalysts were characterized with powder X-Ray Diffraction(XRD),XPS,BET,High-Resolution Transmission Electron Microscopy(HRTEM),X-Ray Fluorescence Spectrometry(XRF) and photoluminescence(PL).The photoactivity of the catalysts was tested by photocatalytic reduction of CO2 with H2O vapor to produce chemically valuable compound including CH4 in self-build experimental set up.The experiment result... |
