High Pressure Nanoscience and Physical Chemistry Group

(HPNanoPC Group)

We study structures, structure changes, physical chemical properties and/or behaviors of both bulk and nano materials at different conditions, including high temperature and/or high pressure. We aim at gaining fundamental knowledge of the systems under study and exploit the obtained knowledge for potential new applications. To conduct our challenging research, we make use of both conventional laboratory instruments and state-of-the-art synchrotron facilities, as well as large-scale molecular simulations.  

Current research interests:

● Syntheses and characterization of high-entropy alloys / oxides / chalcogenides /borides, etc.;

● Developing applications of emerging materials in catalysis and energy conversion;

● High pressure physics and chemistry of novel materials;

● Structures and behaviors of nanomaterials at high pressure;

● Non-classical crystal growth in high pressure conditions.

Li-doped high-entropy oxides (MgCoNiCuZn)O are mixed ionic and electronic p-type semiconductors. The electric conduction mechanism in a wide range of temperatures (79 - 773 K) and at high pressure (up to ~ 50 GPa) was uncovered.  Song et. al., JACS Au (2024).

Simply changing the cation/anion complexity of electrocatalysts can regulate the oxygen evolution kinetics significantly. Li, et al. Angew. Chem. (2022).
