To critically evaluate plasma-assisted methane conversion by linking fundamental electron-impact kinetics and radical chemistry to reactor design, energy efficiency, and industrial scalability.
Synthesized mechanistic literature on non-equilibrium plasma activation, radical generation pathways, and reaction kinetics for methane conversion.
Critically compared major plasma reactor technologies, including dielectric barrier discharge, gliding arc, microwave, and plasma jet configurations.
Identified non-equilibrium plasma activation via energetic electrons as an effective route to cleave stable C–H bonds without high thermal energy inputs.
Demonstrated that reactor design fundamentally controls radical distribution, product selectivity toward hydrogen, syngas, or oxygenates, and overall energy efficiency.
Identified plasma catalysis, operando diagnostics, and modular reactor scale-up as primary frontiers required for commercial implementation.
