A research team led by Prof. Jihwan An from UC Merced and Prof. Haesun Park from Chung-Ang University developed a high-efficiency catalyst for hydrogen production using atomic layer deposition. By applying platinum nanoparticles via plasma-enhanced ALD on 3D structures, the team significantly enhanced the efficiency and durability of Solid Oxide Cells. The catalyst exhibited stable performance at 700°C for 100 hours, showcasing its potential for future energy solutions. This innovative approach addresses the challenges faced by traditional metal catalysts in hydrogen production, offering a promising avenue for sustainable energy. Prof. An emphasized the combination of semiconductor and hydrogen technologies, highlighting the benefits of advanced processes in improving energy device performance. Supported by various entities, including the Ministry of Science and ICT, the study underscores the importance of continued research in advancing clean energy technologies.
