Photocatalytic activity of TiO2 based composite films by porous conjugated polymer coating of nanoparticles

Bio-functionalized hybrid nanocomposite membranes for direct methanol fuel cells

“…It is well-known that nano-TiO 2 is an oxide semiconductor and possess an optical band gap $3.2 eV with l max around 320-380 nm. [31][32][33] Thus, it follows from the absorption results that LY-TiO 2 gets imbibed into PVA matrix.…”

Polymer Coated Functional Catalysts for Industrial Applications

“…Thin films of PVA/TiO 2 were prepared by adding a measured quantity of PVA solution to a TiO 2 solution and the mixture was casted on a glassy substrate, followed by freeze drying and heat treating to produce the conjugated polymer/TiO 2 composites. The PVA/TiO 2 mass ratio and the heat treatment temperature are the major controlling factors for generating composites of the correct porosity [59]. Studies show that coating photocatalysts like TiO 2 with a sacrificial layer of polymeric material can prevent sintering of the catalyst particles during the calcination processes and retain the crystallinity of the photocatalyst without decreasing the specific surface area [60].…”

Synthesis and characterization of poly(p-phenylenediamine): TiO2 nanocomposites and investigation of conducting properties for optoelectronic application

“…Herein, we have reported synthesis and characterization of poly(p-phenylenediamine) -TiO 2 nanocomposite and investigation of a change in conducting behavior of the parent polymer due to formation of nanocomposite. Moreover, TiO 2 nanoparticle based composites also exhibit photocatalytic activity [11] and this fact reflects the possibility of using such nanocomposites for various purposes.…”
