Preparation of Nickel-Gallium based catalysts for carbon dioxide hydrogenation to methanol

Abstract

Abstract Catalytically converting CO2 to methanol by hydrogenation offers a method to effectively reduce the excessive CO2 emission in the atmosphere and produces value-added chemicals simultaneously. Thus, the investigations on catalysts in methanol synthesis reaction has gained attraction in the past few years. Commercial catalysts based on Copper, Zinc, and Zirconium are popular, but increasingly, researchers are looking for other options with superior conversion and selectivity. From prior literature, catalysts based on Nickel and Gallium, specifically a Ni5Ga3 bimetallic catalyst exhibits a similar CO2 conversion and higher methanol yield compared with commercial Copper-based catalysts...
