Dye and bacteria photodegradations with anatase-loaded microporous poly(vinylidene fluoride) membranes

Hierarchical nanofibrous anatase-titania–cellulose composite and its photocatalytic property

“…In recent years, various methods have been reported to prepare hybrid composite materials with titania nanocrystals deposited on the solid substrates, which shows potential application in various fields such as lithium-ion batteries 7 and antibacterial membranes. 8 Various substrates such as silica film, 9 glass 10 and stainless steel 11 were used, however, the dense structures of which lead to the great reduction of the active surface accessible to the solution, resulting in low photocatalytic activities. 12 Cellulose and other polymeric materials used as substrates have been reported in recent years due to the large surface area and good flexibility.…”

Mesoporous TiO2photocatalytic films on stainless steel for water decontamination

“…The photocatalytic performance of the immobilized photocatalyst is critically dependent on the specific surface area. 17,19,[21][22][23] Increasing effort has been devoted to designing porous TiO 2 coating with large surface area, well-crystallized, nanosized anatase, and excellent mechanical stability. 6,7 In this context, mesoporous TiO 2 films have been investigated to display favourable features, such as proper pore-wall parameters for efficient mass exchange, improved light harvesting, 19 as well as superior photocatalytic activities in degrading organic pollutants and inactivating microorganisms.…”

Photocatalytic disinfection of S. aureus using black TiO2−x under visible light

“…Since then, TiO 2 has been shown to be active against various microorganisms. 14,15,[28][29][30] Reactive oxygen species (ROS), developed on the surface of photocatalytic materials under irradiation, are thought to be the cause of these biocidal effects, inducing oxidation of cell membrane components. [31][32][33][34] The mechanisms by which photocatalysts generate ROS have been well established: 12,35 when light of sufficient energy irradiates a photocatalytic material there is a chance for electron-hole pair (EHP) formation.…”
