- 01JHSQJ3CXTCDQA2FGYPTPV7Y6 abstract "Pt:Sn/MgAl2O4 and Pt:In/MgAl2O4 catalysts with 3 wt% Pt and 3 wt% Sn or In were tested for CO2-assisted propane dehydrogenation (CO2-PDH). This reaction was referenced against reverse water-gas shift (RWGS) and non-oxidative PDH, while CO-DRIFTS detailed the nanoparticle (NP) surface. Results were connected to a preceding study, focused on NP material properties using Quick X-ray Absorption Spectroscopy and Temporal Analysis of Products. During CO2-PDH, CO2 was mainly consumed through RWGS. CO2 consumption beyond the RWGS equilibrium arose from carbon oxidation. Promoter oxidation by CO2 and the consequent loss of the Ptbased alloys induced carbon formation. This deactivation increased the in situ CO2:H2 ratio, further accelerating promoter oxidation and carbon formation. Repeated catalyst regeneration cycles increased the promoter concentration in the alloyed NPs. This occurred throughout the entire Pt:Sn NP, while for Pt:In, it was limited to the NP surface with concomitant NP bulk depletion. This promoter enrichment contributed to catalyst deactivation.".
