Abstract
The project is focused on understanding the fundamental and key factors that influence the relationship between the activity, selectivity and stability of hierarchically porous catalyst support structures as well as photocatalytic TiO2-based heterojunction structured materials and their physico-chemical properties. The project aims to describe the relationships between materials’ synthesis parameters and the resulting properties. The activity of the catalysts and photocatalysts will be investigated in terms of CO2 catalytic conversion and CO2 photocatalytic reduction into valuable compounds. The main parameters affecting the reaction rate of hierarchically porous support structures architectures for improved mass transfer properties in the CO2 catalytic conversion as well as the migration pathway of excited electron-hole in the heterojunction photocatalysts used for CO2 photocatalytic reduction will be evaluated and described. Obtained information will lead to a better understanding of structure-activity relationship, which will enable improved design of these materials.
