Chemistry: Cleaner, greener ammonia

Nature 512, 7513 (2014). doi:10.1038/512116d

A method of producing ammonia could yield a greener route to nitrogen-based fertilizers.Ammonia is currently synthesized by combining nitrogen and hydrogen under high pressures and temperatures in a reaction called the Haber–Bosch process. Making the hydrogen consumes around 5% of the world's natural-gas production,
