NO oxidation and reduction
A promising approach to treat NOx in flue gases is to capture and reutilize NOx rather than simply removing it. Our ultimate goal is to develop an innovative technology that transforms harmful NO into useful products, such ammonia (NH3). We are interested in the electrochemical conversion of NO, and it can be implemented either via an electrolytic cell or a galvanic cell. More specific research areas include the development of electrochemical process, electrochemical cell design, and catalyst modifications to improve the reactivity of NO.

Electrochemical NH3 synthesis
Ammonia (NH3) is one of the most used compounds in the world and is used in various fields such as fertilizer. Ammonia, along with hydrogen, has recently been spotlighted as a next-generation energy carrier The potential for ammonia is more highly appreciated due to its lower liquefaction temperature, higher stability and easier of transport than hydrogen. Currently, most of the world's ammonia is produced with Haber-Bosch process, but it has a problem of consuming enormous energy and emitting green-house gas (GHG). To overcome this, studies have been conducted to produce ammonia electrochemically from water and nitrogen. In this laboratory, various approaches are being attempted to increase production efficiency and speed.
