Direct Z-scheme of Cu2O/TiO2 enhanced self-cleaning, antibacterial activity, and UV protection of cotton fiber under sunlight

Environmental effects of stratospheric ozone depletion, UV radiation, and interactions with climate change: UNEP Environmental Effects Assessment Panel, Update 2020

“…A range of nanoparticles are applied either directly to the surface of textile fibres or used in fibre coatings to increase their UV-shielding properties. Most continuing current research on this approach is focused on nanoparticles of zinc oxide (ZnO) [ 462 – 464 ] and titanium dioxide (TiO 2 ) [ 465 – 469 ]. All reported data confirm the efficacy of this approach in increasing UPF of fabrics.…”

“…All reported data confirm the efficacy of this approach in increasing UPF of fabrics. Often, the nanoparticles used are selected for other improvements in fibre quality, such as better antibacterial properties or electrical conductivity, thus creating a multi-functional fabric [ 469 – 472 ]. Other metal oxides, such as NiOx nanoparticles in gas-sensing cotton fibres [ 473 ] and SiOx nanoparticles in superhydrophobic cotton [ 474 , 475 ], are used to obtain specific functionalities, although they also improve UV-shielding properties.…”

Direct Z‐scheme N‐doped TiO2/MoS2 Heterojunction Photocatalyst for Photodegradation of Methylene Blue under Simulated Sunlight

“…However, the CB of TiO 2 (the same as that of N‐TiO 2 ) is more positive than the potential of O 2 / . O 2 − , while the VB of MoS 2 is more negative than the H 2 O/⋅OH potential [48,49] . This means that the electrons accumulated in the CB of N‐TiO 2 cannot convert O 2 to .…”

“…However, the CB of TiO 2 (the same as that of N-TiO 2 ) is more positive than the potential of O 2 / * O 2 À , while the VB of MoS 2 is more negative than the H 2 O/⋅OH potential. [48,49] This means that the electrons accumulated in the CB of N-TiO 2 cannot convert O 2 to * O 2 À , and the holes on the VB of MoS 2 cannot oxidize H 2 O to * OH. This will cause the oxidation ability and photocatalytic performance of N-TiO 2 /MoS 2 composites to be inferior to those of N-TiO 2 .…”

Enhanced Acidic Hydrogen Evolution on TiO2-Doped Gadolinium Electrocatalysts

“…The TiO2-Gd1.0 and TiO2-Gd6.0 NPs were prepared following a previously reported method [9][10][11][12][13][14]. Briefly, titanium (IV) tert-butoxide (5.0 mL) was added to gadolinium(II) nitrate hexahydrate with two different atomic concentrations (1.0. and 6.0%) in DMSO (50 mL).…”
