WELCOME TO THE NANOELECTROCHEMISTRY LABORATORY

SUSTAINABLE ELECTROCHEMICAL AMMONIA PRODUCTION

We aim to develop advanced catalysts for nitrogen reduction reactions (NRR) to realize efficient and selective ammonia synthesis. By designing nanostructures enhanced with transition metals and optimizing stability on conductive supports, our research focuses on achieving high Faraday efficiency, robust activity, and long-term durability, contributing to sustainable energy storage and production systems.

ADVANCED MATERIALS FOR ELECTROCHEMICAL WATER SPLITTING

Our research explores innovative materials for hydrogen generation through electrochemical water splitting. Emphasis is placed on designing transition metal-based oxides, sulfides, and nitrides with tailored nanostructures, improved catalytic activity, and long-term stability, ultimately lowering energy requirements for the oxygen and hydrogen evolution reactions (OER and HER) and enabling scalable, clean hydrogen production.

ALTERNATIVE ELECTROCHEMICAL REACTIONS FOR ENERGY-EFFICIENT HYDROGEN PRODUCTION

Our research explores alternative anodic reactions such as urea oxidation (UOR), hydrazine oxidation (HzOR), and alcohol oxidation to significantly reduce the energy barrier of hydrogen production. By replacing the sluggish oxygen evolution reaction (OER) with thermodynamically favorable processes, we design advanced electrocatalysts that enable low-voltage hydrogen generation. This approach not only improves overall energy efficiency but also integrates environmental remediation with sustainable fuel production.

ELECTROCATALYSTS FOR FUEL CELLS: ENHANCING EFFICIENCY AND DURABILITY

We focus on the design of next-generation electrocatalysts to improve the efficiency and durability of fuel cells. By developing cost-effective alternatives to platinum-based catalysts, employing nanoscale engineering, heteroatom doping, and computational insights, this research aims to overcome challenges such as catalyst poisoning and degradation, ensuring reliable and sustainable energy conversion.
