Photocatalytic oxidation of toluene at indoor air levels (ppbv): Towards a be…

Abstract. We report here a new analytical methodology for the investigation of toluene photocatalytic removal at indoor-relevant concentration level (ppbv). Experiments were performed using an annular flow-through reactor with TiO2 as photocatalyst, toluene as a model VOC and under different ranges of relative humidity (RH: 0–70%), inlet concentration (20–400 ppbv) and flow rate (70–3…
