TL;DR: The characterization results demonstrated that the enhanced catalytic activity was ascribed to several beneficial effects, which were caused by the pre-modification such as the inhibition of crystallite size, improvement of Cr species dispersion and increase of the amount of active sites.

TL;DR: In this paper, the role of chromium oxides and ceria and their synergistic effect in textural properties, redox performance and surface species over the Cr1−xCex/TP catalysts were investigated in detail by means of Brunauer-Emmertt-Teller (BET) surface area analysis, X-ray diffraction (XRD), transmission electron microscope (TEM), temperature-programmed reduction of H2 (H2-TPR), NO-TPD), photoluminescence spectra, and in situ diffuse reflectance infrared

TL;DR: The effects of the morphologies of the prepared 3D ms-BiVO4 superstructure on the photocatalytic oxidation of NO were investigated, indicating that the enhanced photoactivity was not related to the surface area, but associated with the unique morphology, surface structure and good crystallinity.

TL;DR: A series of ceria oxides doped with 20 mol% of Zr, Sn and Ti were prepared by a citric sol-gel method throughout the thermal decomposition of the corresponding metallic propionates as mentioned in this paper.

TL;DR: In this article, a facile and surfactant-free hydrothermal method was used to synthesize cobalt-ceria catalysts with octahedron and nanosphere shapes.
