Crossing the bridge from molecular catalysis to an artificial cell for hydrogen fuel production through time-resolved X-ray spectroscopic approaches
Dooshaye Moonshiram (Ramón y Cajal, ICMM-CSIC)
Abstract: The search for sustainable ways to store and distribute energy is one of the most urgent scientific challenges in view of the rapid depletion of fossil fuels, environmental pollution and resulting climate emergency. A solution to the undergoing energy crisis can only be obtained through implementation of renewable sources and new low-polluting fuels. Solar-driven water splitting provides an efficient means of meeting our energy demands and storing energy in the form of a clean fuel (H2) and oxidant (O2). Hydrogen as an energy carrier further provides an attractive alternative to fossil fuels with its combustion producing only heat and water. The prospect of developing a hydrogen economy and using hydrogen as a carbon-free fuel has motivated the discovery of effective and robust catalysts that can lower the energy barriers to hydrogen production.
However, despite significant efforts, an understanding of these catalysts at a molecular level is still fundamentally lacking due to the limitations of commonly employed methodologies which are not detailed to assign both geometric and electronic structures at their respective reactive high oxidation states. In this context, time-resolved X-ray spectroscopic approaches provide a powerful means of capturing transient intermediate snapshots all the way towards the hydrogen evolution reaction. In this scenario, a laser pulse (pump) initiates a chemical reaction and an X-ray pulse (probe) at varying delays is used to interrogate its evolving electronic and structural response. This talk will demonstrate the reaction pathways of several earth-abundant photocatalytic complexes, examined in unprecedented detail with picosecond time resolution. Results shown will enable the rational design of homogeneous and heterogenized light-harvesters and photocatalysts for an artificial photosynthetic technology with solar to hydrogen efficiencies exceeding the current norm for H2 production from water.
