About the Lab
Professor Hankwon Lim's research lab focuses on sustainable energy technologies, with a strong emphasis on green hydrogen production through advanced electrochemical processes such as proton exchange membrane (PEM) water electrolysis and electrochemical nitrogen or nitric oxide reduction for green ammonia synthesis. The lab develops innovative electrocatalysts and electrolyte systems to enhance efficiency, selectivity, and stability in renewable energy conversion, while also addressing environmental challenges through the upcycling of plastic waste into functional materials for carbon capture. Their work bridges materials science, electrochemistry, and environmental engineering to enable scalable, low-carbon industrial solutions.

15Decarbonizing the planet is one of the major goals that countries around the world have set for 2050 to mitigate the effects of climate change. To achieve these goals, green hydrogen that can be produced from the electrolysis of water is an important key solution to tackle global decarbonization. Consequently, in recent years there is an increase in interest towards green hydrogen production through the electrolysis process for large-scale implementation of renewable energy-based power plants an
The electrochemical N2 reduction reaction has attracted interest as a potential alternative to the Haber–Bosch process, but a significantly low conversion efficiency and a significantly low ammonia production rate stimulate the need for alternatives. Here, we represent the electrochemical reduction of nitric oxide (NO) on a nanostructured Ag electrode in combination with a rationally designed electrolyte containing the EDTA–Fe2+ metal complex (EFeMC), which results in an ∼100% efficiency for NH3
