Aerosol-Assisted Deposition for TiO₂ Immobilization on Photocatalytic Fibrous Filters for VOC Degradation.

ABSTRACT: Atomization and spraying are well-established methods for the production of submicrometer- and micrometer- sized powders. In addition, they could be of interest to the immobilization of photocatalytic nanoparticles onto supports because they enable the formation of microporous films with photocatalytic activity. Here, we provide a comparison of aerosol-assisted immobilization methods, such as spray-drying (SD), spray atomization (SA), and spray gun (SG), which were used for the deposition of TiO₂ dispersions onto fibrous filter media. The morphology, microstructure, and electronic properties of the structures with deposited TiO₂ were characterized by SEM and TEM, BET and USAXS, and UV-Vis spectrometry, respectively. The photocatalytic performances of the functionalize
