Gold Catalysts Supported on the Macroporous Nanoparticles Composited of Cerium Oxide for Oxidation of Formaldehyde
Subscript textSubscript textA series of Au/CeO2 catalysts were synthesized and evaluated for formaldehyde catalytic combustion oxidation. In Au/CeO2 catalysts, CeO2 supports with different structure,Au/Macroporous-CeO2 is found to be superior catalyst for formaldehyde catalytic oxidation. According to the analysis of transmission electron microscopy (TEM), the pore size of Macroporous-CeO2 is broader than that of mesoporous SBA-CeO2 support, which could make the active species gold adequately disperse as small nanoparticles, furthermore, it is most noticed that macroporous CeO2 support is benefit to mass transfer comparing with mesoporous SBA-CeO2 and ordinary power CeO2.
