Stable
catalyst development for CO2 hydrogenation to
methanol is a challenge in catalysis. In this study, indium (In)-promoted
Cu nanoparticles supported on nanocrystalline CeO2 catalysts
were prepared and explored for methanol production from CO2. In-promoted Cu catalysts with ∼1 wt % In loading showed
a methanol production rate of 0.016 mol gCu
–1 h–1 with 95% methanol selectivity and no loss
of activity for 100 h. It is found that the addition of indium remarkably
increases Cu dispersion and decreases Cu particle size. In addition
led to an increased metal–support interaction, which stabilizes
Cu particles against sintering during the reaction, leading to high
stability and activity. In addition, density functional theory calculations
suggested that the reaction is proceeding via reverse water gas shift
(RWGS) mechanism where the presence of In stabilized intermediate
species and lowered CO2 activation energy barriers.
Development of energy-efficient and economically attractive ways of utilization of methane for the production of chemicals/ liquid fuels remains one of the long-standing challenges in catalysis. Li/MgO catalysts synthesized by...
