TL;DR: In this paper, pure TiO 2 anatase particles with a crystallite diameters ranging from 4.5 to 29nm were prepared by precipitation and sol-gel method, characterized by X-ray diffraction (XRD), surface area measurement, UV-vis and scanning electron microscopy (SEM) and tested in CO 2 photocatalytic reduction.

TL;DR: In this article, the catalysts were tested in CO2 photocatalytic reduction and characterized by X-ray diffraction (XRD), nitrogen adsorption measurement and UV-vis.

TL;DR: In this article, the authors present the current state of problem of carbon dioxide emissions from industrial and combustion processes, the principle of photocatalysis, existing literature related to photocatalytic CO2 reduction over TiO2 based catalysts and the effects of important parameters on the process performance including light wavelength and intensity, type of reductant, metal-modified surface, temperature and pressure.

TL;DR: The highest activity is achieved by combination of a number of factors: (i) specific surface area, (ii) adsorption edge energy, (iii) crystallite size, and (iv) efficient separation of the charge carriers, where the efficient separation is the most decisive parameter.

TL;DR: In this article, the effect of silver doping on titanium photocatalyst properties was evaluated by nitrogen physical adsorption, X-ray diffraction, elemental analysis, transmission electron microscopy, Raman spectroscopy, TGA analysis and UV-vis spectrographs.
