Application of Graphene Oxide Aerogel to the Adsorption of Polycyclic Aromatic Hydrocarbons Emitted from the Diesel Vehicular Exhaust

•The adsorption and sieving efficiency of GOA applied to the PAHs emitted from the vehicular exhaust by the dynamometer was first investigated.•More oxidation time enhanced the crystalline structure between the GOA layered sheets.•The carcinogenic BAP adsorption of the GOA was much better than that of XAD resin.•The GOA had better adsorption efficiencies of total PAHs in the engine idling condition.•The GOA adsorbent can be reused after three runs of the Soxhlet extraction and drying.
