The project NEFERTITI is going to develop two connected functionalized flow reactors in a single device for the synthesis of fuels from CO2 and H2O.
Flow Reactor 1 will use enhanced heterogeneous photocatalysts (2-D COFs with Au & RuO2 nanoparticles) to perform the simultaneous conversion of CO2 and H2O, by mimicking Z-scheme photocatalysis found in nature to produce syngas. An adsorbent system will be used to continously remove the generated O2 produced durin the first transformation.
Flow Reactor 2 will use enhanced heterogeneous photocatalysts (Fischer-Tropsch Synthesis catalysts & TiO2) to transform the syngas into ethanol and C2+ alcohols.
HOW TO GET IT?
The reaction mechanisms for the photocatalytic conversion of CO2 / H2O and the formation of C-C bonds will be defined and optimized. NEFERTITI will develop a completely new way of producing such compounds that have an impact on the scientific understanding of this technology.
Modeling of C-C bond formation from activated intermediates will determinate the reaction pathways, barriers and selectivity for C-C, C-O and C-H bonds. By increasing the sunlight conversion efficiency and improving light-harvesting and charge separation, Nefertiti will enable a carbon-neutral production of solar fuels.
OVERCOMING TECHNOLOGICAL CHALLENGES
The light-gathering components and flow reactors will be designed, developed and integrated into a system that achieves a TRL4 at the end of the project.
