Entropy-maximized materials for catalysis applications
ABSTRACT: Until recently the design and synthesis of heterogeneous catalysts have been dominated through enthalpic factors (e.g., charge-charge interactions, charge- transfer interactions). With emergence of high entropy materials (HEMs), another avenue to design and synthesize catalytic materials has opened up. The definition of HEMs is any material that consists of the solid solution of more than five components that allow great flexibility in tuning surface compositions and interfacial functionalities. Here we present the synthesis of high entropy electrocatalysts that potentially outperform the traditional catalysts in energy-related catalysis reactions.1 The synthesis strategies through entropy maximization will be discussed.

BIOE: Dr. Sheng Dai is currently a corporate fellow and section head overseeing four research groups in the areas of separations and polymer chemistry at Chemical Sciences Division, Oak Ridge National Laboratory (ORNL) and a Professor of Chemistry at the University of Tennessee, Knoxville (UTK). His current research interests include porous materials, ionic liquids, and their applications for separation sciences and energy storage as well as catalysis by nanomaterials. His research has led to the 2020 Max Bredig Award for Ionic Liquids and Molten Salts, the 2019 ACS Award in Separation Science and Technology, 2018 IMMA Award given by International Mesostructured Materials Association, Battelle Distinguished Inventor Award in 2016, six R&D100 Awards (2011, 2012, two in 2014, 2015, 2016), and Battelle S&T Challenges Award (2002). He was named DOE Distinguished Scientist Fellow in 2022 because of his exceptional contribution to US DOE energy-related research. He is a Fellow of Material Research Society and Fellow of the American Association for the Advancement of Science.
