A Facile One-Step Synthesis of Polymer Supported Rhodium Nanoparticles in Organic Medium and Their Catalytic Performance in the Dehydrogenation of Ammonia-Borane

Abstract

A new type of supported rhodium nanoparticles were reproducibly prepared from N2H4BH3 reduction of [Rh(mu-Cl)(1,5-cod)](2) without using any solid support and pre-treatment technique. Their characterization shows the formation of well dispersed rhodium(0) nanoparticles within the framework of a polyaminoborane based polymeric support. These new rhodium(0) nanoparticles were found to be the most active supported catalyst in the catalytic dehydrogenation of ammonia-borane in water at room temperature.
