Fast elimination of organic airborne compounds by adsorption and catalytic oxidation over aerosol TiO₂

High concentration TiO₂ aerosol was generated by a sonic method and applied for the first time to air purification from vapors of organic compounds. Reactive adsorption and photocatalytic oxidation over aerosolized TiO₂ nanoparticles result in complete elimination of acetone and dimethyl methylphosphonate vapors over the timescale of few minutes, which demonstrates a good prospect of this novel method for practical air treatment.
