Reductive Treatment of Ga-Pt-Supported Catalytically Active Liquid Metal Solutions (SCALMS) for Propane Dehydrogenation.

ABSTRACT: A comprehensive investigation of the impact of hydrogen (H₂) pretreatments on Ga-Pt supported catalytic active liquid metal solution (SCALMS) for propane dehydrogenation (PDH) is reported. Our approach bridges from model system investigations to real-world catalytic systems, which are tested in continuously operating PDH reactors. The microscopic and spectroscopic findings on model Ga-Pt systems suggest changes in the electronic structure and surface chemistry during SCALMS sample oxidation and H₂ pretreatment, indicating potential modifications of the active sites involved in PDH. H₂ pretreatments of technical Ga-Pt SCALMS prepared by ultrasonication (US) led to significantly improved activity, i.e., the conversion of propane increased from 10% for the unt
