Probing the Electronic, Atomic and Nanoscale Structure of Ni-Ga/SiO2 Catalysts for CO2 Hydrogenation to Methanol Via Operando X-Ray Absorption Spectroscopy and X-Ray Total Scattering

Here, we present a detailed structure-performance analysis of Ni-Ga/SiO2 catalysts under CO2 hydrogenation conditions using operando X-ray absorption spectroscopy and X-ray total scattering. The use of these complementary techniques is key to characterize the structure of the active phases in the Ni-Ga system across the electronic, atomic and nanoscale
