TL;DR: In this article, samples of iron-doped titania containing different amounts of iron (0.5 − 5 ¼ ) were prepared from TiCl4 and Fe(III) acetylacetonate by the sol-gel method.

TL;DR: In this paper, structural and surface features of powder iron-doped titania photocatalysts have been investigated by applying a variety of complementary techniques: temperature programmed desorption-mass spectrometry analysis, non-isothermal thermogravimetric analysis, differential thermoanalysis, infrared spectroscopy, scanning electron microscopy and X-ray diffraction analysis.

TL;DR: In this article, a new TiO2 catalysts have been synthesized by means of a sol-gel method in which aggregates have been selected before thermal treatment, in which Sieving and calcination temperature have been proved to be key factors in obtaining catalysts with greater photoactivity than that of Degussa P-25.

TL;DR: In this paper, the effect of annealing temperature in the final surface and structural properties of ZnO nanoparticles has been investigated, and it has been stated that calcination treatments lead to a significant improvement in the photocatalytic properties of the studied samples, even better than TiO 2 (P25).

TL;DR: In this paper, the Pt-ZnO catalysts (0.5 or 1.0 Pt wt.%) were obtained by photochemical deposition method on the surface of the prepared ZnO sample, using hexachloroplatinic acid (H2PtCl6).
