将V2O5, CeO2和CuO分散到提取自稻米壳的SBA-16上,考察了其催化CO氧化反应活性,并采用X射线衍射、扫描电镜、透射电镜、程序升温还原和紫外漫反射光谱对所制催化剂进行了表征。结果表明,掺杂CuO的介孔氧化硅是一种有前景的催化剂,其CO转化率可达98%以上。
V2O5, CeO2, and CuO were dispersed on rice husk derived SBA-16, and the CO oxidation activities of these systems were examined. The catalysts were characterised using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, temperature-programmed reduction, and diffuse reflectance ultraviolet spectroscopy. The CuO doped mesoporous silica was identified as a promising catalyst. More than 98%of CO conversion was achieved over the system.
