Photocatalytic CO2 reduction over TiO2/rGO photocatalysts
Original language description
Abstrakt z konference 28th IUPAC Symposium on Photochemistry, která se konala ve dnech 17. - 22. 7. 2022 v AmsterdamuIn this work, a conversion of carbon dioxide (CO2) into methane, carbon monoxide as well as hydrogen was investigated in presence of TiO2/rGO photocatalysts. Photocatalysts were prepared in two-steps: solvothermal method and calcination at 500, 800 and 1000 oC in argon atmosphere. The obtained samples were characterized by XRD, UV-Vis/DRS, N2 adsorption-desorption and analysis of carbon content. The activity of photocatalysts was evaluated in the reduction of CO2. The TiO2/rGO-10 without calcination showed the highest activity toward CO2 conversion while all rGO modified samples exhibited higher activity and selectivity toward H2 generation in comparison with starting-TiO2 as well as reference materials. It should be pointed that the highest selectivity of H2 production was achieved by samples consisting of rutile. Moreover, it was found that selected photocatalyst after rGO modification and calcination was quite stable. The enhancement of activity was attributed to the efficient charge separation and prolonged recombination time of charge carriers resulting from rGO content.
