Spin State-Engineered Magnetic Catalyst for Water Oxidation Under External Magnetic Field
What
This project focuses on enhancing the oxygen evolution reaction (OER) in alkaline water electrolysis through catalyst spin-state engineering and the application of an external magnetic field. It elucidates how catalyst spin states influence OER kinetics, establishes design principles for efficient electrocatalysts, and advances the mechanistic understanding of spin-dependent catalytic processes.
Why
Improving water electrolysis efficiency is essential for sustainable hydrogen production and the clean energy transition. A key challenge is the sluggish OER, driven by a complex four-electron transfer process and a spin-state mismatch between reactants (H2O/OH–) and triplet oxygen (O2). This project investigates whether catalyst magnetism and external magnetic fields can accelerate OER kinetics.
How
In this project, metal oxide catalysts based on earth-abundant magnetic elements, such as Fe, Co, and Ni, will be developed. Their OER performance under external magnetic fields will be evaluated through electrochemical characterization and computational studies. By revealing magnetic effects on catalytic pathways, the project will establish design strategies for efficient electrocatalysts.
