Abstract:
A novel protocol for the preparation of Rh-decorated TiO2 photocatalysts with the rhodium content of 0.01–1.0 wt% has been developed based on the deposition of the low-soluble hydrogarnet type salt Ca3[Rh(OH)6]2. Under 380-nm irradiation in water–ethanol mixtures the photoinduced reduction of Ca3[Rh(OH)6]2/TiO2 results in the formation of highly active Rh/TiO2 photocatalysts with nanoparticulated rhodium co-catalyst preferably attached to the surface of anatase particles. The catalysts generate up to 21 mol of H2 per gram of rhodium per hour via a photocatalytic hydrogen evolution reaction (HER) outperforming the activity of the analogous materials reported to date.
