Photocatalytic splitting of water into oxygen and hydrogen constitutes a key requirement to realizing the successful use of hydrogen as a clean energy source and was recently identified by the European Science Foundation as one of the world’s emerging key research fields. Light-driven conversion of CO2 into chemical commodities for industrial production of fine chemicals would equally benefit our environment and economy. In search for a better photocatalyst, substantial research has been devoted to downscaling of size and increasing specific surface area, tuning of morphology, and modifying its electronic structure.
Hybridization of nanocarbon materials, i.e. CNTs and graphene, with active inorganic nanomaterials constitutes a powerful strategy towards designing new-generation functional materials for applications where efficient charge separation and extraction is required such as photocatalysis. The next challenge is to design photocatalysts with large mesopores arranged in an ordered 3D-interconnected pore architecture. We design these materials through a self-assemble- assisted process using tailor-made triblock-terpolymers as structure-directing agents and sacrificial templates. I will demonstrate how mesostructuring and hybridization with nanocarbons can further advance photocatalysts.
