Comparison of the catalytic performance of Au/TiO2 prepared by in situ photodeposition and deposition precipitation methods for CO oxidation at room temperature under visible light irradiation

As compared with Au/TiO 2 -DP, the Au/TiO 2 -PD sample showed more electron transfer from TiO 2 to Au sites, more activation of O 2 induced by oxygen vacancies, and the more obvious photo-promoting effect induced by the LSPR effect.
