Development of Cu-based hybrid catalysts for the electrocatalytic CO2 reduction to added value products. The simultaneous need to reduce greenhouse gas emissions and increase our energy supply makes the electrochemical reduction of CO2 a very attractive alternative. In this context, science seeks effective methods to transform CO2 into chemicals of economic value. Among the possible products to obtain, we are especially interested in species with one or more carbon-carbon bonds, these types of compounds are favored using copper as catalyst. Although some other catalysts can produce this type of bond, none it does with the same efficiency as copper. This thesis is developed in the exposed context, analyzing six catalysts synthesized with different ratios of Cu, Zn and Al2O3 and subsequently exposed to a thermal treatment to obtain C-based oxygenates from CO2.
