Effect of Acidity, Basicity and ZrO2 Phases of Cu-Ni/ZrO2 Catalysts on the Direct Synthesis of Diethyl Carbonate from CO2 and Ethanol

Cu-Ni/ZrO2 catalysts with different Cu:Ni molar ratios were synthesized and tested in the direct synthesis of diethyl carbonate from carbon dioxide and ethanol. The effect of Cu:Ni molar ratio on the acidity and basicity of the catalysts was investigated using NH3 and CO2-TPD, respectively. Experime...

The effect of Cu:Ni molar ratio on the acidity and basicity of the catalysts was investigated using NH3 and CO2-TPD, respectively. Experimental results revealed that Cu:Ni-3:1/ZrO2 and Cu:Ni-2:1/ZrO2 samples exhibited the largest acidity and basicity, as well as the highest yield to diethyl carbonate. In particular, these catalysts displayed very-high selectivity (i.e., larger than 95 %) and activity (i.e., equilibrium conversions are attained). Additionally, XRD and Raman studies showed that structural and crystalline properties of ZrO2 were modified with Cu:Ni ratios of 3:1 and 2:1 (Cu:Ni-1:1/ZrO2, Cu:Ni-1:2/ZrO2) which was related to the improved catalytic activity in comparison to Cu:Ni-1:1/ZrO2, Cu:Ni-1:2/ZrO2, Cu:Ni-1:3/ZrO2 and ZrO2. © 2016 Springer Science+Business Media.oscar.arbelaez@campusucc.edu.co733-725Springer New York LLCCarbon dioxideCarbonationCatalyst activityCatalyst selectivityCatalystsEthanolZirconiaZirconium alloysBimetallic catalystsCrystalline propertiesDiethyl carbonatesDirect synthesisEquilibrium conversionHigh selectivityMolar ratioRaman studiesNickelEffect of Acidity, Basicity and ZrO2 Phases of Cu-Ni/ZrO2 Catalysts on the Direct Synthesis of Diethyl Carbonate from CO2 and EthanolArtículohttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/publishedVersionCATAL LETTinfo:eu-repo/semantics/closedAccesshttp://purl.org/coar/access_right/c_14cbPublication20.500.12494/41383oai:repository.ucc.edu.co:20.500.12494/413832024-08-20 16:21:13.396metadata.onlyhttps://repository.ucc.edu.coRepositorio Institucional Universidad Cooperativa de Colombiabdigital@metabiblioteca.com
