Innovative photocatalytic reactor for the degradation of VOCs and microorganism under simulated indoor air conditions: Cu-Ag/TiO2-based optical fibers at a pilot scale

This study deals with photocatalytic application for indoor air pollution remediation. Two target compounds were selected: Butane-2,3-dione (C4H6O2) and Heptan-2-one (C7H14O). Escherichia coli (E. coli) used as bacteria strain. Photocatalytic removal of VOCs alone, E. alone their mixture (VOCs/E. evaluated, at pilot scale. Indeed, a series experiments carried out in continuous planar reactor using novel photocatalyst/TiO2 technology metal wires e.g. Copper (Cu)/Silver (Ag)-woven optical fiber. Effects experimental conditions such flow rate (2–12 m3.h?1), inlet concentration (5–20 mg.m?3) humidity levels (5–70%) on efficiency investigated to properly appraise the oxidation performance real conditions. All textile fiber photo-catalysts (TiO2, TiO2-Cu TiO2-Ag) showed good activities towards C4H6O2/C7H14O removal. As simultaneous coli: (i) terms efficiency, same trend was observed compared alone: 63% by TiO2 46% TiO2-Ag 52% TiO2-Cu, (ii) inactivation, only revealed performance.
