Morphology-dependent Ni/TiO2 catalysts for CO2 hydrogenation

Abstract

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.
