AI Summary

Researchers at the National University of Singapore developed a catalyst‑regeneration strategy that keeps platinum‑based catalysts effective during electrochemical ammonia cracking. The approach prevents surface oxidation and nitrogen blockage that normally reduce catalyst activity. In laboratory tests, the regenerated catalysts sustained hydrogen production for more than 2,000 hours. The study shows that ammonia, which can store and transport hydrogen without emitting carbon dioxide, can be converted to hydrogen and nitrogen using electricity in a more reliable, energy‑efficient process.
