Nitrogen & Nitrate Reduction Electrocatalyst Development
We develop advanced catalysts for efficient nitrogen (N₂) and nitrate (NO₃⁻) reduction,
focusing on highly active, selective, and stable materials for sustainable chemical conversion.
By engineering catalyst composition, surface structure, electronic properties, and active sites,
our research aims to promote nitrogen fixation and nitrate remediation under energy-efficient
conditions. These innovations offer promising pathways toward sustainable ammonia production, clean energy technologies, and removal of nitrate pollutants from water, contributing to a cleaner
and more sustainable future.
Low-PGM/non-PGM Electrocatalysts with low-temperature fuel cells and Zn–air batteries
We develop low-PGM and non-PGM catalysts for low
-temperature fuel cells and Zn–air batteries, with a
focus on reducing dependence on costly platinum-
group metals while maintaining high electrochemical
performance. Through rational catalyst design, defect
engineering, and interface engineering, our research
targets highly active and durable catalysts for oxygen
reduction (ORR) and oxygen evolution (OER).
These materials aim to deliver improved efficiency,
stability, and cost-effectiveness for next-generation clean energy conversion and storage technologies.
Advanced electrode and electrolyte materials for aqueous Zn-ion batteries
We develop advanced electrode and electrolyte materials for
aqueous Zn-ion batteries, with a focus on achieving high
energydensity, long cycle life, fast ion transport, and enhanced
safety. Our research explores high-capacity and structurally
stable electrode materials together with engineered aqueous
electrolytes that regulate Zn²⁺ transport, suppress undesirable
side reactions, and improve electrochemical stability.
These innovations aim to enable low-cost, safe, sustainable,
and scalable energy-storage systems for next-generation
applications.
Advanced electrode and electrolyte materials for aqueous Zn-I2/Zn-S batteries
We develop advanced electrode and electrolyte materials for
aqueous Zn–I₂ and Zn–S batteries, targeting high energy
density, fast reaction kinetics, long cycle life, and improved
safety. Our research focuses on engineered iodine and sulfur
cathodes, conductive host structures, and functional aqueous
electrolytes to address challenges such as polyiodide/polysu
lfide shuttling, electrode degradation, Zn dendrite growth,
and parasitic side reactions. These innovations aim to
establish safe, cost-effective, high-performance, and sustainable aqueous energy-storage technologies.
