In industry, methanol synthesis using the catalyst CuO/ZnO/Al2O3 occurs at a high pressure. We intend to make certain modification on the traditional catalyst to work at lower pressure, maintaining high selectivity. Therefore, three heterogeneous catalysts were synthesized by coprecipitation to improve the activity and the selectivity to methanol under mild conditions of temperature and pressure. Certain modifications on the traditional catalyst Cu/Zn/Al2O3 were employed such as the modification of the synthesis time and the addition of Pd as a dopant agent. The most efficient catalyst among those tested was a palladium-doped catalyst, 5% Pd/Cu/Zn/Al2O3. This had a selectivity of 64% at 210 °C and 5 bar. info:eu-repo/grantAgreement/ES/MICINN/CTQ2016-76533-R info:eu-repo/grantAgreement/ES/MICINN/PID2019-106196RB-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.501 2021 CHEMISTRY, PHYSICAL 71 / 165 = 0.43 2021 Q2 T2 0.728 2021 Physical and Theoretical Chemistry 2021 Q2 Catalysis 2021 Q2 5.5 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lasobras Laguna, Javier Universidad de Zaragoza (orcid)0000-0003-1940-9597 Soler, Jaime (orcid)0000-0002-7488-6196 Herguido, Javier Universidad de Zaragoza (orcid)0000-0002-2494-102X Menéndez, Miguel Universidad de Zaragoza (orcid)0000-0001-9022-2835 5005 555 Universidad de Zaragoza Dpto.
