Self-decontaminating layer-by-layer functionalized textiles based on WO3-modified titanate nanotubes. Application to the solar photocatalytic removal of chemical warfare agents

WO3-modified TiO2 nanotubes for photocatalytic elimination of methylethylketone under UVA and solar light irradiation

“…7a showed a signal that could be fitted with only two components, related to the Ti 2p spin-orbit components of Ti 4+ surface species [47]. Comparison between the different samples revealed a consistent binding energy shift of 0.9 eV towards higher binding energies between dried TiNT and WO 3 -modified TiNT material.…”

Spray‐Assisted Polyelectrolyte Multilayer Buildup: from Step‐by‐Step to Single‐Step Polyelectrolyte Film Constructions

“…These nanotubes were incorporated into poly(ethyleneimine)/TiNT multilayers obtained by alternate spraying of TiNT and PEI solutions onto textiles. [80] The use of the spray deposition method led to homogeneous coverage of the textile fibers in contrast to the dipping based LbL which resulted in a non-homogeneous coverage where fibre surfaces covered by particle aggregates alternated with naked zones with no deposited material ( Figure 16).…”

Indoor Decontamination Textiles by Photocatalytic Oxidation: A Review

“…The titanium dioxide nanoparticles have been synthesized by various methods, including nonaqueous sol-gel route at low temperatures [23], microemulsions using hydrothermal method [24,25], solvothermal method by monodisperse nanoparticles [24,25], micelle and inverse micelle methods using microemulsions [26], layer by layer method (immersing into two different solutions) [27,28], layer by layer method (using two sprays) [29], direct oxidation methods at lower temperatures [30], chemical vapor deposition method [31], physical (thermal) vapor deposition method [32], anodic oxidative hydrolysis or electrodeposition method [33], ultrasonic spray pyrolysis (sonochemical method) [34], ultrasonic induced agglomeration [35], and conventional and microwave-hydrothermal deposition methods [36]. The detailed study convening synthesis, properties, and modifications as well as applications of titanium dioxide nonmaterial is already presented [37]; this study focuses on general applications of titanium dioxide nanoparticles rather than particular application on textiles.…”
