Abstract

We report a catalyst-free, one-step strategy utilizing double dielectric barrier discharge to convert CH₄ and H₂O into light alcohols under ambient conditions, achieving 8% methane conversion and 70% light alcohol selectivity. Mechanistic analysis verifies that the dominant pathway for alcohol formation is the direct coupling of alkyl and hydroxyl radicals.
