Studies on the Conversion of Atmospheric Carbon Dioxide to Methanol
… atmospheric CO₂ to methanol (MeOH), covering catalysts to support the selective synthesis of MeOH and approaches to interface intermittent renewable power with the production of methanol. For thermochemical hydrogenation of CO₂ to methanol, copper-based catalysts are the most established …

Scaling down direct dimethyl ether synthesis for biogas conversion
… over CuO/ZnO/Al203 (CZA) and 1 % Au/CeZr04 catalysts and it was found that the gold based catalysts are superior to the copper based catalysts for low temperature WGS. The kinetics of the WGS reaction over fresh gold based catalyst and the deactivation kinetics model was then studied. It was …

Energy Conversion Materials: Computational Design of Electrocatalysts Toward Sustainable Energy Applications
… and electronic properties that govern a catalysts’ activity and selectivity. In this thesis, we start by exploring 48 reconstructed transition metal dichalcogenides edges (MX<sub>2</sub>, M = Mo, W; X = S, Se, Te) for carbon dioxide reduction reaction as an alternative to copper-based …

Copper-based nanostructured catalysts for efficient and selective CO2 electroreduction – synthesis, catalytic performance, and mechanistic analysis
… (e.g., solar and wind). Among various materials, copper-based catalysts are most studied, given their unique capability to make hydrocarbons in considerable amounts and at reasonable overpotentials. In this thesis, in-depth understanding of the CO2 electroreduction process was firstly established …

Zeolite encapsulated metal complexes as heterogeneous catalysts for oxidation reactions
… of zoilite-Y generates new heterogeneous catalysts. These catalysts were synthesized employing the flexible ligand method encapsulation technique.The structures of these encapsulated complexes were established on the basis of various physico-chemical and spectroscopic studies. The results …

Simultaneous production of methanol and dimethylether from synthesis gas
… of methanol by hydrogenation of CO/CO2 over a copper based catalyst and subsequent dehydration of methanol to DME over an acidic catalyst. Alternatively, DME can be produced in an one-step (direct) process using a hybrid (bifunctional) catalyst system that permits both methanol synthesis and …
