Abstract

Due to the greenhouse effect, which is related to the increase in the level of CO2 in the atmosphere, capture, storage and utilization technologies have been extremely important and have received global attention in recent years. As a result, there is growing pressure to reduce CO2 reduction, as well as the development of efficient systems for capturing and using it. From this perspective of catalytic systems, the CO2 converter can be developed into technological materials with added value, as a goal of interest for the development and maintenance of life. Cerium, zirconium, copper and nanostructured materials are extensively studied due their catalytic properties and for their high chemistry and thermal stability. Structural and morphological modification can be obtained by changing the synthetic methods and conditions to oxide obtention. In metallic catalysts, the decrease in size of the particle cause an increasing of the surface atoms number, modifying the interfaces interactions, oxidation state and interactions between oxides, mandatory for the formation of active sites. Based on this information, the goal of this work is to obtain bimetallic nanoparticles for application in catalytic hydrogenation of CO2 to methanol. The nanoparticles will be obtained by porous inorganic Polymer synthesis (3D), post synthetic modification and pyrolysis. The aim is to obtain systems with finely controlled morphology, size and composition, with subsequent evaluation of the relationships between the observed structural characteristics and the catalytic properties of solids for application in CO2 hydrogenation systems with preferential methanol production.
