CO2 hydrogenationIndium oxideYttriumLanthanumSupported indium oxide catalysts are investigated for the CO2 hydrogenation to methanol at a total pressure of 40bar (528–573K) using a laboratory flow reactor. Sur
The direct hydrogenation of CO2 into methanol is crucial for providing a means of CO2 fixation 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 ...
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 hydrogenation of CO2has attracted much attention in recent years, because it not only serves to mitigate the problem of anthropogenic emissions of CO2but also provides a feasible avenue for carbon recycling and hydrogen energy conversion or storage1,2,3,4. Among the various hydrogenation p...
It must be pointed out that, while asymmetric hydrogenation of β-keto carboxylic esters is a well known procedure, there was only one previous example of catalytic hydrogenation of β-keto acids reported by Genêt et al. [92]. Scheme 25. Synthesis of chiral β-hydroxycarboxylic acids (...
we summarize the state of the art advances and perspectives in direct CO2hydrogenation to methanol and other higher alcohols. We focus on the catalyst design, mechanistic investigation and the structure-performance relations of two categories of catalysts, noble metal and non-noble metal. Then, we ...
Mixed metal oxide catalysts capable of catalyzing hydrogenation of carbon dioxide to methanol reaction are disclosed, as well as a method for producing methanol from carbon dioxide and hydrogen. The mixed metal oxide catalysts include copper (Cu), and M1 and M2 oxides. M1 can be zinc (Zn), ...
The presence of water as a solvent together with methanol have effectively enhanced the performance of the catalyst. The mechanistic routes for CO 2 hydrogenation to formic acid are proposed and discussed by the kinetic and experimental observations....

The hydrogenation of CO2 to methanol is one of the most promising ways to reduce the CO2 emission and mitigate the energy shortage, but it still confronts low CO2 conversion and methanol selectivity. In this work, the Cu/Al2O3, Cu/AlCeO and Cu/CeO2 catalysts with 60 wt.% Cu were ...
