Cover Feature: Graphene-Based Material Supports for Ni− and Ru− Catalysts in CO2 Hydrogenation: Ruling out Performances and Impurity Role (ChemSusChem 23/2024)

Abstract

The Cover Feature shows graphene nanoplatelets (Gnp) as catalyst support for Ni or Ru and their use in CO₂ hydrogenation. The prepared heterogeneous catalyst is deeply characterized by assessing catalytic performances, quantifying particle size and sulfur content, and evaluating carbon loss during catalyst pre-reduction. The Ru-based catalyst shows almost complete selectivity towards the reverse water gas shift reaction (rWGS), while the Ni-based catalyst also produces methane (methanation). More information can be found in the Research Article by G. Garbarino and co-workers. Cover design and realization: Renza Merlo Belviso and Gabriella Garbarino.
