The direct hydrogenation of CO2into methanol is crucial for providing a means of CO2fixation and a way to store cleanly produced hydrogen in a more energy-dense and transportable form. Here we have prepared two series of Pd/ZnO catalysts, both by immobilisation of PVA-protected Pd colloids and...

catalysts are the most efficient for the CO2hydrogenation to DME via the one-step coupling process. In this case, the metal-based catalysts, such as Cu/ZnO/Al2O3catalyze the hydrogenation of CO2to methanol while the acid sites, such as HZSM-5 dehydrate the intermediate methanol to form DME...
Catalytic transformation of CO2 to formate is generally realized through bicarbonate hydrogenation in an alkaline environment, while it suffers from a thermodynamic sink due to the considerable thermodynamic stability of the bicarbonate intermediate. Her
Although considerable progress has been made in carbon dioxide (CO2) hydrogenation to various C1 chemicals, it is still a great challenge to synthesize value-added products with two or more carbons, such as gasoline, directly from CO2 because of the extreme inertness of CO2 and a high C–C ...

it would be highly desirable to develop alternative fuels from non-fossil fuel sources and processes. The products of CO2hydrogenation such as methanol and hydrocarbons are excellent fuels in internal combustion engines, and are easily stored and transported. Furthermore, methanol is a raw material ...
Boosted CO2hydrogenation to methanol was achieved by introducing appropriate amount of Au into conventional Cu-based catalysts. The AuxCu/ZnObimetallic catalystswith various Au/Cu molar ratio (x = 0.001, 0.005, 0.02 and 0.05) were prepared by the co-precipitation method, among which the Au0.005Cu...
