Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

The Adsorption of VOCs by Honeycomb Ceramics Loaded with Molecular Sieves

“…ere are two general methods for controlling VOCs emission content: recycling technology and destruction technology [5].…”

Modeling of indoor air treatment using an innovative photocatalytic luminous textile: Reactor compactness and mass transfer enhancement

“…In photocatalysis TiO 2 was used in different forms such as nanoparticles suspension [16], nanotubes [17] and film/nanoparticles deposited onto different substrates [9, . The advantage of supporting nanoparticles on substrates is that it eliminates the need to separate catalyst particles from solution after treatment [20,[24][25][26][27][28][29][30].…”

“…The optical fibers are distributed to ensure uniform side emitting light throughout the fabric. This maximizes the contact with the photocatalyst (TiO 2 ) which is directly deposited on the surface of the textile and allows a better distribution of the photons [28,29]. Several studies of optical fiber coated with TiO 2 have studied the impact of fiber diameter and thickness of TiO 2 layer [8].…”

Synthesis and Characterization of TiO2 Nanotubes (TiO2-NTs) Decorated with Platine Nanoparticles (Pt-NPs): Photocatalytic Performance for Simultaneous Removal of Microorganisms and Volatile Organic Compounds

“…Based on these results, Pt presents a high bacterial inactivation capability. Undoubtedly, visible light could improve the stimulation of electron transfer between Pt and bacterial cells, which leads to the formation of reactive oxygen species (ROS), resulting in microorganism inactivation [ 7 , 45 , 46 , 47 ]. In their previous investigations, Abidi et al [ 33 ] indicated that the contact between some metals, such as copper species and microorganisms’ cells, led to the extraction of electrons from cells, which allows for protein denaturation.…”

“…In addition, TiO 2 -NTs present an excellent antibacterial activity under UV irradiation due to the photogeneration of electron/hole pairs, resulting in ROS generation (OH • , O 2 −• , etc.) [ 7 , 33 , 46 ].…”
