• NANOELECTROCHEMISTRY LABORATORY

Research at NECL is highly interdisciplinary, bridging across fields such as electrochemistry, analytical chemistry, materials science, nanotechnology, and surface chemistry. Our endeavors are currently centered on developing various aspects of nanomaterials through methods like wet chemistry synthesis and electrochemical techniques. Our research focuses on several interconnected domains.

• 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.

• 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.
