Abstract

Considering that the increase of CO2 emissions in recent years is an environmental threat concern for the Earth's climate, the great challenge is to find efficient alternatives to reduce the level of CO2 through processes of removal, sequestration, use and conversion. This proposal aims to improve the performance of photocatalytic/photoelectrocatalytic reactors on CO2 reduction into fuel, testing Ti/TiO2 nanotubes and nanowires decorated with metallic nanoparticles of Cu, Pd, Ag, Au e Pt, in order to contribute to the study of: (i) CO2 recycling, (ii) mitigation of atmospheric CO2, that is closely associated with global warming, (iii) creating highly sustainable and renewable energy sources, and (iv) find new ways to transform CO2 into higher-added value products. Therefore, the intended project look for synthesize, characterize and apply new semiconductor materials in the form of Ti/TiO2 to lead the reduction of CO2 efficiently and sustainably using UV and visible light, as well as potential gradient. Considering that one of the CO2 limitations conversion studies in aqueous medium it's the low solubility at ambient temperature and pressure, it's intended to improve the performance of CO2 conversion in aqueous medium developing photocatalytic/photoelectrocatalytic reactors operant in ionic liquids medium and high pressure.
