Lab Overview
Computational Catalysis & Emerging Materials Lab (CCEL) is dedicated to the development of advanced materials and catalysts for electrocatalysis, thermocatalysis, solid oxide fuel cells, and Li-based batteries.
We utilize cutting-edge computational techniques and experimental characterizations to analyze material properties and elucidate structure-properties relationships.
Our works include the design of novel catalysts for CO2 reduction, hydrogen production, and C1 chemistry, as well as atomic engineering for novel material design including exsolution, dopant engineering and morphology engineering.
Additionally, we focus on the development of materials for energy storage, specifically redox flow batteries and Li based batteries, by developing composite electrolytes and assessing the impact of additives on battery performance.
Our lab's primary goal is to employ computational methods to design and create new materials and catalysts for a diverse range of applications, with an emphasis on electrocatalysis, energy storage, and sustainable chemistry.
