Plasma catalysis in ammonia production and decomposition: Use it, or lose it?

The combination of plasma with catalysis for the synthesis and decomposition of NH3 is an attractive route to the production of carbon-neutral fertiliser and energy carrier, and its conversion into H2. Recent years have seen fast developments in the field of plasma-catalytic NH3 life-cycle. This work summarises the most recent advances in plasma-catalytic and related NH3-focussed processes, identifies some of the most important discoveries, and addresses plausible strategies for future developments in plasma-based NH3 technology.
