Subscript text Subscript 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.

Catalytic oxidation desulfurization of gasoline is a key process for the utilization of petroleum hydrocarbons. However, the inherent mechanism still remains unclear and the kinetic investigation is usually performed in processes with limited mass transfer rates. Herein, the kinetics and mechanism of catalytic oxidation of sodium ethyl mercaptide were investigated with microfluidics. On the basis of eliminating mass transfer resistance, the effects of temperature, pressure, residence time, and gas-liquid flow ratio on the oxidation were assessed. According to the results of UV-vis spectra and binding constant, it was confirmed that the catalytic center was in the form of dimer. A heterogeneous reaction kinetic model was proposed as such. The kinetic parameters close to intrinsic kinetics and corresponding kinetic rate expression were obtained.
