The way to beneficially recycle CO2, which is a greenhouse gas and a very stable molecule, under mild conditions and produce syngas could be with the use of light and an active catalyst. In my thesis, basic concepts are clarified in light of this: from the thermodynamics of the examined reaction and the catalyst composition at the nanoscale, as well as the influence of light and localised suface plasmonic resonnance (LSPR), to experimental approaches for the interpretation of typical photocatalytic test results. In the last part, the major drawbacks for the implementation in the industry and the most efficient photocatalysts are presented.
