Abstract: To achieve the goals of CO2 reduction set for 2030 and 2050, there is a considerable interest in developing possible CO2 transformation processes that can be performed at large scale, for instance, for the production of fuels. However, CO2 reactions are typically very slow and require high temperatures to be performed at a decent reaction rate. One alternative is to promote the reactions using solar light as energy source. The presentation will describe different photocatalytic systems developed at the Institute of Chemical Technology of Valencia to perform CO2 hydrogenations using simulated sunlight. The materials described include photo-responsive metal-organic frameworks, supported metal nanoparticles and 2D materials. The objective of the presentation is to summarize the state of the art on photocatalytic CO2 hydrogenation and to show how far or close are to develop a possible commercial process.
