In my research field, I am focusing on soft X ray absorption spectroscopy for studying the surface reaction mechanism. Recently new SXAS technic for measurement of liquid-solid interphase was been tested and needed to be further investigated. In long time, due to the short mean free path of electron in the liquid materials, XAS can be only detected by the fluorescence technic which give the bulk information. New technic for liquid environment XAS measurement can give us solid-liquid interphase surface information, which can help us further understand the liquid phase heterogeneous reaction mechanism. In this future, I want to continue the research on SXAS technics which can be a promising tool to understand unknow chemical reaction mechanism to help other researchers to develop more efficient catalysts.
