Hydrophobic RWGS catalysts: Valorization of CO2-rich streams in presence of CO/H2O 2023 Access copy available to the general public Unrestricted Nowadays, the majority of the Reverse Water Gas Shift (RWGS) studies assume somehow model feedstock (diluted CO2/H2) for syngas production. Nonetheless, biogas streams contain certain amounts of CO/H2O which will decrease the obtained CO2 conversion values by promoting the forward WGS reaction. Since the rate limiting step for the WGS reaction concerns the water splitting, this work proposes the use of hydrophobic RWGS catalysts as an effective strategy for the valorization of CO2-rich feedstock in presence of H2O and CO. Over Fe-Mg catalysts, the different hydrophilicities attained over pristine, N- and B-doped carbonaceous supports accounted for the impact on the activity of the catalyst in presence of CO/H2O. Overall, the higher CO productivity (4.12 μmol/(min·m2)) attained by Fe-Mg/CDC in presence of 20 % of H2O relates to hindered water adsorption and unveil the use of hydrophobic surfaces as a suitable approach for avoiding costly pre-conditioning units for the valorization of CO2-rich streams based on RWGS processes in presence of CO/H2O. info:eu-repo/grantAgreement/ES/MICINN/PID2020-113809RB-C31/AEI/10.13039/501100011033 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.2 2023 CHEMISTRY, APPLIED 13 / 74 = 0.176 2023 Q1 T1 ENGINEERING, CHEMICAL 35 / 170 = 0.206 2023 Q1 T1 CHEMISTRY, PHYSICAL 60 / 178 = 0.337 2023 Q2 T2 1.022 2023 Chemistry (miscellaneous) 2023 Q1 Catalysis 2023 Q2 11.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion González-Castaño, M.
