• Green hydrogen production technology, which utilizes renewable energy to produce eco-friendly hydrogen without carbon emissions, is gaining attention as a core technology for addressing global warming. • Green hydrogen is produced through electrolysis, a process that separates hydrogen and oxygen by applying electrical energy to water, requiring low-cost, high-efficiency, high-performance catalysts.
Article Summaries:
- Researchers have developed a single‑atom catalyst that can simultaneously drive both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) in water electrolysis, the key process for green hydrogen production. The atomically precise material-composed of isolated metal atoms anchored on a conductive support-offers high catalytic activity, stability, and lower cost compared with conventional multi‑component catalysts. By enabling efficient, low‑energy water splitting with a single catalyst, the breakthrough could simplify reactor designs, reduce material usage, and accelerate the deployment of renewable‑energy‑driven hydrogen as a carbon‑free fuel.
