中文摘要：

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．

英文摘要：

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 activity than Au/Fe-O cata- lysts prepared by co-precipitation （CP） at same gold weight percentage content. It was found that hexahedron FeOOH loaded nano gold superior to Fe2O3 , which played an important role at the activity of formaldehyde catalytic oxidation.
