TiO2 supported gold clusters are prepared by photo-deposition method. The effect of preparation parameters on the size and morphology of gold clusters are investigated. The as-prepared Au/TiO2 samples are characterized by means of ICP, XRD and TEM. Au/TiO2 samples with different gold cluster sizes are studied as possible catalysts in the selective oxidation of benzyl alcohol to benzaldehyde and smaller gold clusters are observed to exhibit higher catalytic activity.

Supported Gold

Activated carbon supported gold nanoparticles (Au/C) were prepared by a chemical reduction process using NaBH4as a reducing agent. The characterization of transmission electron microscope indicated that the Au nanoparticles (AuNPs) in the Au/C catalyst were highly well dispersed on the carbon support. The catalytic activity of the Au/C catalyst for the methanol electrooxidation (MEO) was investigated by the cyclic voltammetry (CV). The results displayed that the Au/C catalyst exhibited a favorable catalytic activity towards the MEO in alkaline solution. Moreover, the competitive adsorption between OH-and CH3OH on the surface of the AuNPs in the Au/C catalyst existed in the course of the MEO. Based on this competitive adsorption, the mechanism of the MEO on the Au/C catalyst was further investigated.
