Generation of ZnCu nanoparticles from Cu-Zn-Al hydrotalcite-type
Abstract
The emission control of greenhouse gases is taking great scientific relevance today due to climate change. The transformation of CO2 to CH3OH using Cu-Zn/alumina catalysts is a solution to CO2 emission mitigation. A technological and scientific research priority. CuZn dispersion on Al2O3 catalytic supports needs improvement. Therefore, through calcination and reduction processes, a large dispersion of Cu and CuZn metallic nanoparticles with a size of around 5 nm was achieved on an Al-O surface using hydrotalcite clay. A material with great capacity to accept Cu+2 and Zn+2 into its structure. The hexagonal morphology of the hydrotalcite platelets remained unchanged, as did the chemical composition. Therefore, Cu-Zn-Al catalysts with three metallic charges of Cu and Zn were obtained, ready to be evaluated in the reaction of CO2 to CH3OH.
