Comparative Evaluation of HFC‐134a Decompositions Over Metal‐Impregnated γ‐Al2O3 Catalysts (M/γ‐Al2O3) (M = Mg, Ni, Co, Zn, Cu)

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study examines the impact of an impregnated metalon the structural alterations of the catalyst induced by intermediatesgenerated during the HFC‐134a catalytic decomposition reaction. Through adetailed analysis of the catalyst before and after the reaction, the underlyingcause of the observed inactivity is elucidated.

Mitigating Green Oil Deactivation in Acetylene Hydrogenation Using Carbon‐Supported Pd Catalysts

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study reveals that carbon‐supported palladium catalysts outperform alumina‐supported ones in resisting deactivation during acetylene hydrogenation. Carbon nanotubes prove exceptionally stable, while graphite deactivates rapidly. Catalyst surface area, not green oil formation, emerges as the key factor in deactivation rates.

Effective CO2 Decomposition in a Nonthermal Atmospheric Pressure Plasma Jet System Coupled with CuO Catalysts

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The plasma–catalyst system facilitates both homogeneous (plasma‐only) and heterogeneous (plasma–catalyst) CO2 decomposition. Initially, CO2 molecules are dissociated by plasma‐generated energetic species, while long‐lived reactive species further interact with the plasma‐activated CuO catalyst to enhance CO2 decomposition.
