TL;DR: It is demonstrated that the presence of both the high-energy {001} oxidative and low-energy{101} reductive facets in an optimum ratio is necessary to reduce the charge recombination and thereby enhance photocatalytic activity of TiO2 NCs.

TL;DR: Combined glancing-incidence X-ray diffraction and depth-profiling X-Ray photoelectron spectroscopy studies show that these NPs have a crystalline core-shell structure, with a face-centered cubic metallic Cu core and a simple cubic Cu2O shell with a CuO outerlayer.

TL;DR: In this article, the Ag and Au-doping effects on the fundamental nature and photocatalytic activity of BiOCl and biOCl x I 1−x were investigated in detail.

TL;DR: In this article, a review of recent progress in CO2 reduction using titanium oxide-based materials and various strategic factors for increasing photocatalytic efficiency is presented. But, the reduction efficiencies and selectivities of these reactions are insufficient for practical use, and significant effort and strategy are required to overcome the many obstacles preventing the large-scale application of photocatalyst-based CO 2 reduction.

TL;DR: In this paper, the authors synthesized echinoid-like BiOI microspheres with various doped concentrations of Ag (0.1, 1, 1.0, 5.5, 10.0), Ti (1.0 and 5.0 mol%) in ethylene glycol and then examined their fundamental properties by scanning electron microscopy, transmission electron microscope, X-ray diffraction analysis, UV-visible absorption, FT-IR, Raman, photoluminescence and Brunauer-Emmett-Teller (BET) surface
