OBJECTIVES

To achieve the project objectives, the following specific activities will be implemented by each partner:

1.   Carbonaceous@TiO2 photocatalysts (UA, UTBV, UNIFESP):

Thin layers of titanium dioxide will be grown on activated carbon structures with well-defined porous structures and modified with graphene or graphene derivatives to act as a heterojunction.

Emphasis will be placed on designing synthesis methods to enhance the photocatalytic activity of the materials, particularly in the visible light range compared to pure titanium dioxide.

2.   Z-type photocatalytic systems (UTBV, UA, UNIFESP, EPI):

Z-type photocatalytic systems will enhance the performance of single-component photocatalysts by utilizing visible light.

These systems will be used for the degradation of pollutants in water and air and for CO2 conversion.

3.   Photocatalyst applications (UA, UNIFESP, UTBV, EPI):

Photocatalytic systems with applications in degrading pollutants in water and air and photocatalytic CO2 conversion address global challenges related to energy and the environment.

Photocatalytic reduction of CO2 remains a challenge due to low solar energy conversion efficiency.

4.   Integrated reactor (EPI, UTBV, UNIFESP):

3D printing technology will be used to manufacture monolithic catalysts that can effectively address issues encountered under normal operating conditions.

A small-scale reactor (1L-10L) will be prototyped to operate in continuous flow conditions in solid-gas/solid-liquid environments.

5.   Product life cycle and environmental aspects (UTBV, UA, UNIFESP, EPI):

Economic, social, and environmental aspects will be assessed through life cycle assessment (LCA) and SWOT analysis to identify the impact of the proposed materials and technologies.
