HyMAP aims at developing a new generation of multifunctional hybrid photocatalysts and solar photoreactors which would allow the exploitation of at least 1 % of the sunlight energy for the CO₂ photoreduction using water as electron donor. HyMAP proposes an interdisciplinary research program through which several breakthroughs at different scales will be achieved: i) development of efficient multifunctional organic/inorganic semiconductors and metal-organic frameworks as photocatalysts with separated reduction/oxidation active sites; ii) characterization and modelling of the structural and opto-electronic properties of the proposed materials; iii) evaluation of the materials in artificial photosynthesis devices.
