Abstract The detailed study regarding the formation of nanocomposites with high photoelectrochemical activity for hydrogen (H2) evolution as well as the reduction of carbon dioxide (CO2) in high added value compounds (CO, CH4, CH3OH, HCOOH, ethanol) is proposed. Since environmental and energy problems are among the most challenging issues facing the humanity nowadays, the development of efficient catalysts for the production of renewable fuels has become crucial. Thus, the main objectives of this project are: (i) to synthesize and characterize tin oxides in different oxidation states (SnO and Sn3O4), as well as their nanocomposites involving reduced graphene oxide (rGO) and also graphitic carbon nitride (g-C3N4); (ii) to evaluate the photoelectrochemical performance of these materials in order to produce high added value compounds; (iii) to determine/quantify the possible products generated and to investigate the mechanisms involved in CO2 reduction and H2 evolution. The catalysts will be examined by various characterization techniques, including X-ray diffraction, scanning and transmission electron microscopy, Infrared and Raman spectroscopies. This proposal will provide valuable information for the development of improved catalysts, contributing to the environment, academic and industrial interests. In addition, the candidate will be in contact with renowned researchers and research centers (BEPE) under the co-supervision of Prof. Dr. Krishnan Rajeshwar, allowing to her to acquire new knowledge, contributing to the interests of the UNESP-Araraquara research groups.
