Hermenegildo García - Getting closer to a large scale process. Photocatalysts for light-assisted CO2 hydrogenation

There is an urgent need to diminish atmospheric CO2 emissions to meet with the International agreements on global warming and climate change. One of the possible strategies is the utilization of CO2 as feedstock of fuels and chemicals. Among the possible reactions, CO2 hydrogenation can give a wide variety of products from methane to light hydrocarbons and alcohols of high added value. However, due to its high chemical stability, CO2 transformation requires a considerable amount of energy to run the reaction at temperatures above 450 oC and high pressure. In this context, the use of solar light as primary energy source and development of selective photocatalysts to promote the reaction becomes highly relevant. The presentation will summarize the contribution of the group to develop efficient solar photocatalysts for selective CO2 hydrogenations, indicating the targets to be achieve to be competitive with conventional thermal catalytic processes and the possibility to achieve these goals in short term.
