Single-atom platinum catalyst unlocks carbon-free ammonia heat for steel, cement and chemicals

"ammonia difficult to burn cleanly/ efficiently: high > 500°C ignition, nitrogen oxide pollution, only burns within tight fuel-to-air ratio range making unstable for large-scale industrial furnaces... overcome isolating platinum atoms anchored to heat-stable support enabling 200°C ignition, withstand/ maintain steady 1,100°C combustion... output: pure nitrogen, water vapor... drop-in/ existing infrastructure/ global commodity... catalyst becomes more stable after first high-temperature run, handles 24/7 cycles"
