| Resumo: | Climate change caused by carbon dioxide anthropogenic emissions has turned into one of the most important environmental concerns of our society. Among the different actions proposed for mitigation of CO2 emissions, electrocatalytic reduction appears as a very promising technology for recycling CO2 to synthetic fuels and other valuable products. One of the most important challenges of this technology is the development of catalysts that allow obtaining high efficiencies in the reduction of the CO2 molecule. This work is focused in the development of Cu based nanostructured catalysts deposited on carbon supports. Supercritical fluid deposition (SFD) technique has been used for the copper deposition on three different carbon supports: carbon black (CB), carbon nanotubes (CNT) and reduced graphene oxide (rGO). SFD is an environmentally friendly technology that has demonstrated good results in the synthesis of nanomaterials. |
