Resumo

Fe 2 TiO 5 is a promising and underexplored material as a semiconductor photocatalyst for CO 2 reduction reaction (PCO 2 RR), aimed at mitigating greenhouse gas emissions. In this study, pure Fe 2 TiO 5 was synthesized via solvothermal method and subsequently calcined across temperatures ranging from 600 to 900 degrees C. The performance was evaluated within a PCO 2 RR under simulated sunlight, generating CH 4 as a single detectable product. Further enhancement was achieved by depositing CuO nanoparticles below 5 nm onto the Fe 2 TiO 5 surface using magnetron sputtering deposition. The yield of CH 4 increased from 0.032 to 0.042 mu mol. As far as we know, this marks the inaugural application of Fe 2 TiO 5 as a photocatalyst for CO 2 reduction. (AU)
