Promoters are able to modulate the performance of catalysts for a given process, but this can be done through various mechanisms. Here the role of Mn as a promoter on Fe-based catalysts for CO2 hydrogenation to olefins is comprehensively investigated via spectroscopic and kinetic analyses. The promoter induces a restructuring of the catalyst surface, balancing the strength of the adsorption of reactants and intermediates.
