Abstract

Sub-nanometer Pt@Rh nanoparticles highly dispersed on MIL-125-derived porous TiO₂ nanoplates are successfully prepared for the first time by a photochemical route, where the porous TiO₂ nanoplates with a relatively high specific surface area play a dual role as both effective photoreductant and catalyst support. The resulting Pt@Rh/p-TiO₂ can be utilized as a highly active catalyst.

Keywords: core-shell structures; heterogeneous catalysis; photochemical route; porous titania; sub-nanometer particles.
