Abstract

A precise synthesis of small (<2 nm) supported palladium-gallium alloyed nanoparticles on GaIII sites dispersed on silica (PdGa@SiO2) is reported. This material, prepared via a Surface Organometallic Chemistry (SOMC) approach, is highly active and selective in hydrogenation of CO2 to methanol.
