Synthesis and Characterization of Nanomaterials: Catalytic Application

These days, the world is undergoing major economic development, which is generating strong growth in energy demand. The use of fossil fuels leads to high emissions of greenhouse gases, in particular CO_2, which is harmful to the environment and to humanity, hence the idea of harnessing the latter to produce clean, sustainable energy. In this context, catalysts based on copper and zinc metal oxides (CuO and ZnO) supported on aluminium oxide Al₂O₃ and titanium oxide TiO₂ were synthesised at different calcinations temperatures of 350°C and 450°C in order to activate the CO₂ hydrogenation reaction to form methanol.
