Hydrogenation is an important mechanism in converting CO2 into useful chemicals, such as methanol, methyl formate, and diethyl ether. Hydrogenation requires suitable catalysts to yield product within feasible production conditions. Heterogenous catalysts, Iron (Fe-), Copper (Cu-), and Nickel (Ni-) based catalyst, which are favoured in industrial applications but have lower yield and selectivity processes using homogenous catalysts.
This invention is a homogenous catalyst—Ruthenium (Ru-), Rhodium (Rh-), and Iridium (Ir-) based—that effectively reduces, cleaves, and/or couples C=O, C=C, or C=N bonds. The catalyst system comprises tin, which is inexpensive and abundant, for hydrogenation process. The system has multiple advantages over existing technologies, including an ability carry out the reaction in non-aqueous base solvents, which would offer higher CO2 conversion rate. In addition, the system is also stable at high temperatures, up to 125°C.
