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...
