Plausible reaction mechanism for photoreduction by Pt/TiO2 nanocomposite in presence of H2PtCl6 and ethanol as a sacrificial donor. Treatment of PtCl6 with aqueous medium gives the [Pt(OH)6]2− ions, the steps are as follows in path 1 at valance band as shown in above scheme. [Display omitted] •It ma...
