Catalytic oxidation of formaldehyde over CeO2-Co3O4 catalysts

CeO2-Co3O4 with Co/(Co+Ce) ratio of 0.95 achieved a 100% conversion of HCHO at 80 °C; The addition of CeO2 enhanced specific surface area and fine dispersion of CeO2-Co3O4; The interaction between CeO2 and Co3O4 improved the reducibility and surface active oxygen
