2021.09.01 Breaking Ammonia: A New Catalyst to Generate Hydrogen from Ammonia at Low Temperatures

Ammonia, a carbon-free resource can be split into nitrogen and hydrogen gas with the help of metal catalysts like Nickel (Ni). However, these reactions often require very high operating temperatures. Now scientists from Tokyo Institute of Technology (Tokyo Tech) have developed a highly efficient calcium imide (CaNH)-supported Ni catalyst that can decompose ammonia at temperatures 100°C lower than what conventional Ni catalysts require. This promising new catalyst can get us closer to sustainably producing hydrogen fuel.
