An aqueous-phase catalytic process for the selective hydrogenation of acetylene with monodisperse water soluble palladium nanoparticles as catalyst

Abstract

We report herein an aqueous-phase catalytic process with palladium(0) nanoparticles (PdNPs) stabilized by semi-natural water soluble cellulose as catalyst. PdNPs stabilized by sodium carboxymethyl cellulose (CMC) in water were a very efficient and stable catalyst in the aqueous-phase catalytic process for the selective hydrogenation of acetylene under mild reaction conditions. This work demonstrates the possibility of developing an aqueous-phase catalytic process using a durable and environmentally benign catalyst.
