Rh(0)/Rh(iii) core–shell nanoparticles as heterogeneous catalysts for cyclic carbonate synthesis

Abstract

Rh(0)/Rh(III) core–shell nanoparticles were prepared by surface oxidation of Rh nanoparticles with N-bromosuccinimide. They were employed as heterogeneous catalysts for cyclic carbonate synthesis from propylene oxide and CO₂, and exhibited high activity and excellent recyclability due to Lewis acidic Rh(III) species on the shells.
