TL;DR: It was found for the first time that decreasing the relative concentration ratio of bulk defects to surface defects in TiO(2) nanocrystals could significantly improve the separation efficiency of photogenerated electrons and holes, thus significantly enhancing the photocatalytic efficiency.

TL;DR: In this article, a supported TiO2 film was synthesized by sol-gel method and further sensitized by CdS nanoparticles using a sequential chemical bath deposition technique, and the degradation efficiency reached 92.8% and 32.7% under UV-vis and visible light irradiation, respectively.

TL;DR: In this article, the presence of densely populated mesopores in the microcuboid CeO2 nanocubes results in highly reactive surface lattice oxygen due to the exposure of the mesopore wall surface with high interfacial curvature, thus leading to a significant enhancement in catalytic activity.

TL;DR: In this article, the evolution of chemical functional groups, microstructure and water barrier properties of polyamide-cured epoxy (diglycidyl ether of bisphenol-A epoxy resin, DGEBA) coating during ultraviolet A (UV-A) photo-oxidative aging is systematically investigated.

TL;DR: In this article, the effect of the ionized impurity scattering and dislocation scattering on the performance of nano ZnO photocatalysts was investigated, and it was found that the effect is most probably attributed to the effects of the impurities and dislocations scattering.
