Research in Zhenxing Feng's group focuses on three main directions: (1) Energy storage, conversion and harvesting; (2) Catalysts for electrochemical and chemical reactions; (3) Development and application of advanced synchrotron based X-ray techniques for in situ time-resolved studies.

We have been working on lithium-sulfur, lithium-ion and beyond lithium-ion (such as magnesium batteries, etc.) for storing electricity in chemical and electrochemical forms. In order to improve the energy harvesting and conversion efficiency, we study catalysts using both model systems and real materials to figure out their intrinsic descriptors that govern materials chemical and electrochemical properties. As the gas/solid, liquid/solid, and solid/solid interfaces in these energy systems are critical parts where many important reactions take place, we develop and apply advanced synchrotron X-ray techniques, including scattering, spectroscopy, imaging, and pump-probe methods at different national user facilities (e.g., Advanced Photon Source in Argonne National Lab, Advanced Light Source in Lawrence Berkeley National Lab, National Synchrotron Light Source II at Brookhaven National Lab), to understand the interfacial processes during operational conditions. The learned mechanistic insights, in turn, have helped us to further design many energy materials in rational ways.
