NOVELTY - Utilizing light-plasma coupling to process polluted air, comprises (1) dissolving graphene oxide (GO) in methanol and stripping by using a probe sonicator for 30 minutes, adding cerium oxide (CeO2) under vigorous stirring, and mixing with ammonia solution, pouring into 100 ml Teflon(Polytetrafluoroethylene) container, loading into a stainless steel autoclave and subjecting to hydrothermal reaction in a vacuum furnace, allowing to cool naturally, washing with ultralight water, and drying, (2) dispersing rGO/CeO2 nanocomposite in deionized water, ultrasonicating, adding α-pinene into dispersion and stirring, and ultrasonically treating α-pinene, centrifuging, and drying, (3) filling α-pinene composite rGO/CeO2 nanoparticles evenly into catalyst chamber on inner wall of plasma reactor, and introducing air polluted by nitrogen oxides, and (4) passing the treated exhaust gas through the plasma reactor again, and obtaining air treated by optical plasma coupling. USE - The method is useful for utilizing light-plasma coupling to process polluted air. ADVANTAGE - The method ensures the plasma treatment generates radiation to excite the light source, drives the speed of photocatalytic reaction to accelerate, photocatalytic reaction to nitrogen oxides, improves the charge transport performance and removal effect of α-pinene composite rGO/CeO2 catalyst for nitrogen oxides, and during the photocatalytic process, hydroxy and water on the surface of α-pinene composite rGO/CeO2 catalyst react to generate hydroxy radicals, hydroxy radicals will react purely with nitrogen oxides, α-pinene contains a special bicyclic double bond structure, and the aromatic ring on rGO and the carbon-carbon double bond of α-pinene will be π-π stacked.
