Strong metal-support interaction between Ni and BaCO3 boosts CO2 hydrogenation

Abstract

In the current issue of Chem Catalysis, Zhu and co-workers report the construction of a neotype strong metal-support interaction between Ni nanoparticle and BaCO₃ via H₂ reduction and CO₂ hydrogenation. The migration of BaCO₃ onto Ni nanoparticles leads to the formation of porous overlayers, which not only stabilized the Ni nanoparticles against sintering but also formed abundant Ni-BaCO₃ interfaces for CO₂ enrichment, thereby enhancing CO₂ hydrogenation to methane.
