摘要：

By identifying the Electron Partitioning Effect (EPE) as responsible for the large gold deposits usually formed in the conventional photodeposition method, a low energy UV light-based method for the preparation of comparatively high-activity gold-titania catalysts was developed. These materials were tested in the carbon monoxide (CO) oxidation reaction and returned markedly higher levels of activity at room temperature, when compared to catalysts prepared by the traditional photodeposition method. This is the first instance of using a light-mediated process for preparing catalysts active for the CO oxidation reaction.
