Researchers at the National University of Singapore (NUS) have developed a catalyst-regeneration strategy that could make hydrogen production from ammonia more efficient and reliable. By tackling a major problem that causes catalysts to lose their effectiveness over time, the team sustained hydrogen production for over 2,000 hours in laboratory tests.
