Pt-Doped Ru Nanoparticles Anchored on 'Black Gold' for Enhanced Hydrogenations/Reductions Including Semi-Hydrogenation Reactions

Abstract

A hybrid catalytic nanoreactor having selectivity and stability in presence of air is provided for reduction reactions including semi-hydrogenations comprising of light harvesting dendritic plasmonic colloidosomes (DPC) of gold preferably as black gold and co-acting synergistically active catalytic sites of Pt-doped Ru bimetallic nanoparticles for desired significantly special selectivity and air-stability as a plasmonic reduction catalyst favoring plasmon-mediated simultaneous reduction and oxidation of metal active sites for facilitating reduction reactions including semi-hydrogenation activity. Said black gold/RuPt catalyst showcases good efficiency in acetylene semi-hydrogenation, attaining over 90% selectivity with ethene production rate of 320 mmol g−1 h−1 with its stability evident from 100 h of operation with continuous air flow, attributed to the synergy of co-existing metal oxide and metal phases. The catalyst's stability is further enhanced by plasmon-mediated concurrent reduction and oxidation of the active sites, facilitating its end use and applications in chemical industries, petrochemical industries, and applications catalysis.
