Green synthesis approach for preparing zeolite based Co-Cu bimetallic catalysts for low temperature CO2 hydrogenation to methanol

• Green synthesis of zeolite based Cu-Co bimetallic catalysts for methanol production in slurry reactor. synergism over CO 2 hydrogenation to has not yet been reported the literature. Structure-activity relationship methanol. In this study, were synthesized by green deposition precipitation method. To investigate optimum metal-metal ratio, with different metal weight ratios evaluated The XRD analysis revealed crystalline nature support highly dispersed oxides. FESEM observation showed well morphology catalysts. nitrogen adsorption-desorption studies that surface area was slightly decreased increasing Cu content Temperature program reduction exhibited between metals which resulted variation behavior Similarly, XPS interaction shifting peaks higher binding energies regions. desorption investigations existence three types basic sites on Activity profiles examined low temperature activity documented enhancement rate from 7.5 25.6 g/Kg cat .h Based physico-chemicals findings and data, structure-activity patterns elaborated details.
