Investigation of process parameters for solar fuel production using earth-abundant materials

Journal of CO2 Utilization

September 2023

Photoreduction of COto solar fuels and chemicals offers a sustainable method to produce net zero energy vectors. For large-scale applications, it is crucial to develop an improved understanding of the influence of reaction conditions on the design and optimisation of the photoreactor. The performance of CuO impregnated on BaTiO3 photocatalyst was investigated and compared to pristine BaTiO3, and CuO impregnated on commercial P25 (CuO/P25) and ZnO. The influence of irradiance, COand H2O flow and partial pressure, and CO2/ H2O ratio on the product yield and selectivity were all examined. This work reveals that the combination of catalyst design, reaction engineering, and modelling can improve the efficiencies of COphotoreduction.
