Title:
Enabling soft X-ray spectroscopy for in-situ/in-operando study of photocatalytic and electrochemical reactions

Abstract:
In many important energy systems such as energy conversion and energy storage, advanced materials and fundamental interfacial phenomena play crucial roles in device performance and functionality due to the complexity of material architecture, chemistry and interactions among constituents within. To understand and ultimately control the interfaces calls for in-situ/in-operando characterization tools in which soft X-ray spectroscopy offers many unique features. In this presentation, I will report the development of in-situ reaction cells for soft x-ray spectroscopic towards the studies of photosynthesis, catalytic and electrochemical reactions. Some of the instrumentation design and experimental studies are given as the examples, e.g. the experiment for studying the hole generation and dynamics of photoelectrochemical catalysts under in-operando conditions.
