| Abstract Scope |
Solar energy conversion, such as solar fuel catalysis, is an intricate process that involves multiple reaction steps and timescales of electron and proton transfers. To better understand the fundamental mechanisms underlying this process, our team has developed a suite of multiple-timescale, pump-probe X-ray spectroscopy and scattering (MTX) capabilities at the Advanced Photon Source (APS). These tools enable the investigation of structural dynamics during energy conversion processes, across a broad range of timescales, from hundreds of picoseconds to microseconds or longer. I will share several recent studies that utilized MTX to track photo-induced electronic and structural changes in emerging photoactive materials.
The recent APS upgrade will deliver X-ray beams with substantially improved brightness and coherence. The second part of the presentation will focus on the recent development and future opportunities of time-resolved capabilities motivated by the upgraded APS along with their applications in studying structural dynamics in emerging energy materials. |
