TL;DR: In this paper, the authors give an overview of the development and implications of nanotechnology in photocatalysis, including the use of nanoparticles in doped, coupled, capped, sensitized and organic-inorganic nanocomposite semiconductor systems, with an effort to enhance photocatalytic and optical properties of commonly used semiconductor materials.

TL;DR: In this article, the presence of small silver particles on the titania surface of TiO 2 particles was found to enhance the photooxidation of high loadings of sucrose and salicylic acid.

TL;DR: In this paper, the photocatalytic reduction of selenium anions, selenate (Se(VI)) and selenite (Se-IV) to elemental seenium (Se) over UV-illuminated TiO2 was performed using formic acid, acetic acid, methanol, ethanol, sucrose and salicylic acid as the organic hole scavengers.

TL;DR: In this article, a stable magnetic photocatalyst was prepared by coating a magnetic core with a layer of photoactive titanium dioxide, which inhibited the direct electrical contact and hence prevented the photodissolution of the iron oxide phase.

TL;DR: In this article, a modified alkoxide method was used to extract nanocrystalline titanium dioxide (TiO2) particles under acidic conditions at temperatures ranging from 60°C to 90°C.
