| 摘 要： | 采用溶胶沉积法、共沉淀法制备了负载型Au/Fe-O催化剂,运用X-射线粉末衍射(XRD)、透射电镜(TEM)、电感耦合等离子原子发射光谱(ICP-AES),比表面和X射线光电子能谱(XPS)技术对其进行了表征,考察了Au/Fe-O催化剂对甲醛的催化氧化活性.金负载量相同的条件下,溶胶沉积法制备的样品甲醛催化氧化活性好于共沉淀法制备的样品.实验结果表明:六面体的FeOOH载体担载了较多活性组分纳米金,是影响甲醛催化氧化活性的主要原因.

| Abstract: | Au/Fe-O catalysts were prepared by colloidal deposition (CD) and co-precipitation (CP) methods. These samples were characterized by means of X-ray diffraction(XRD), transmission electron microscopy techniques (TEM), inductively coupled plasma atomic emission spectrum(ICP-AES), specific surface and X-ray photoelectron spectroscopy(XPS). Catalytic oxidation reactions of formaldehyde were investigated. The results showed that Au/Fe-O catalysts prepared by colloidal deposition (CD) exhibited better catalytic ac... |
