Morphology-Dependent Ni/TiO2 Catalysts for CO2 Hydrogenation

This work investigates the effect of the chemical states of similarly sized Ni nanoparticles on CO2 hydrogenation. Characterization results indicate that a higher concentration of weakly basic sites favors CO2 activation and oxidized Ni species benefit selective CO2 hydrogenation to CO. Ni/TiO2{001} is an efficient catalyst for CO production.
