Ammonia (NH3) has received increasing attention in recent years as a potential hydrogen energy carrier

attributed to its high hydrogen storage density and relatively low costs associated with storage and transportation in the field of green hydrogen production. Plasma technology

characterized by its non-equilibrium nature

high reactivity

and adaptability to low temperatures

provides a promising and innovative technical pathway for hydrogen production via ammonia decomposition. We summarize recent research progress in atmospheric pressure plasma-assisted ammonia decomposition for hydrogen generation.Moreover

we elucidate the influence laws of discharge parameters (voltage

frequency

power)

work gas (composition

flow rate

pressure)

and reactor configuration (electrodes

dielectric materials) on ammonia conversion efficiency and product distribution. The existing mechanisms underlying the synergistic effects between plasma and catalysts are also analyzed. Current research indicates that plasma technology can significantly reduce the ammonia decomposition temperature (as low as 400 ℃) and enhance the activity of non-noble metal catalysts. However

further key works in energy efficiency and scalability for practical applications are still required. By outlining the key technical bottlenecks of plasma-assisted ammonia -to- hydrogen

future research directions are put forward

including plasma parameter optimization

reaction pathway refinement

and a deeper understanding of catalyst-plasma synergistic mechanisms.
