New Iron Catalyst Doubles Green Hydrogen Production Efficiency
Updated June 02, 2025
A collaborative research team has achieved a breakthrough in lasting energy by developing a novel iron-based catalyst. This new catalyst more than doubles the efficiency of thermochemical green hydrogen production, marking a notable advancement in the field.
With concerns mounting over pollution and climate change, hydrogen is emerging as a clean energy alternative. Thermochemical water splitting, which uses heat to separate water into hydrogen and oxygen, holds particular promise. Metal oxides play a crucial role in this process by absorbing and releasing oxygen.
Conventional oxides, however, require extremely high temperatures, hindering their practical submission. The research team, including Professor Hyungyu Jin from POSTECH and Professor Jeong Woo Han from Seoul National University, addressed this limitation by creating an iron-poor nickel ferrite (NFO) catalyst. Unlike traditional oxides that rely on small oxygen absorption, this ferrite exhibits a phase conversion mechanism, enabling greater oxygen capacity at lower temperatures.
The experimental results demonstrated a water-to-hydrogen conversion efficiency of 0.528% per gram of oxides, surpassing the previous benchmark of 0.250%. The findings were published in Acta Materialia.
Beyond developing the high-efficiency catalyst, the team also successfully identified the “structural active sites” within iron oxide materials that drive hydrogen production at the atomic level. They discovered that a redox swing between two types of iron sites directly correlates with hydrogen yield.
“This study is meaningful in that it proposes an economical and sustainable hydrogen production pathway using abundant iron oxides,” said Professor Hyungyu Jin. “It also opens the door to using solar heat or industrial waste heat as energy sources for hydrogen generation.”
Professor Jungwoo Han added, “This work is a compelling exmaple of how experimental and computational sciences can work together to uncover fundamental principles through interdisciplinary collaboration.”
What’s next
The researchers plan to use thes insights to design even more effective catalysts, potentially unlocking further gains in green hydrogen production and contributing to a more sustainable energy future. The study highlights the potential of thermochemical water splitting.
