Effect of promoters on the performance of Cu-based catalysts in CO2 thermocatalytic hydrogenation

CO2 rational utilization nowadays is one of the most important goals for the scientists and engineers due to the global warming. The problem is that the CO2 molecule is very stable and difficult to convert to other compounds. In this respect, transformation of CO2 into CO via the reverse water gas shift (RWGS) reaction is a promising route, because the resulting carbon monoxide can be used as a feedstock to produce various value-added chemicals1.

CO2 valorisation via the RWGS route.

At the same time, the thermodynamics of RWGS are favourable only at elevated temperatures and low pressure since otherwise CO2 methanation and methanol production reactions take place. However, for practical applications a high pressure and low temperatures are required to reach higher productivity. Another issue is that mainly noble metal catalysts, such as Pd- and Pt- based systems, are used for this reaction due to their stability in severe conditions, but their practical application is hindered by the high cost. In the case of non-precious metals, Cu-based catalysts have been considered as promising candidates for this reaction because of the high activity, selectivity, and relatively low cost.

Copper, using it alone, possesses noticeable hydrogenation ability that can drive the reaction towards either hydrocarbons or methanol. Hence, promoters are necessary to direct the process to the desirable route. My work is dedicated to the investigation of the effect of different promoters on the structure, performance, and stability of Cu-based catalysts in RWGS reaction at high pressure. To achieve it, study of Cu-promoter interactions, effect of promoter nature and concentration will be realized.
