The following operating parameters listed below have been shown to influence CO2 photoreduction: type of reductant, temperature, pressure and particle size. These factors are discussed in the following sections. 3.1. Effect of reductant Several types of reducing agents such as H2O, NaOH, and C3H7...
Through electrostatic interaction and high-temperature reduction methods, rGO was closely coated onto the surface of TiO2 nanotubes. Even at a high temperature of 700 °C, the nanotube morphology of TiO2 (anatase) was preserved because of the assistan
The low-temperature epitaxy of rutile TiO2films on VO2-templated substrates was locally visualized by comparing cross-section high-resolution transmission electron microscope (HRTEM) images of both TiOx(x< 2)/TiO2and TiO2/VO2/TiO2(Fig.1c, e). Amorphous nature of TiOxfilms on TiO2was confirmed...

It was also found that cerium species are more active in the low temperature NO-SCR reaction than tungsten ones (NO conversions obtained at 300 °C using CeO2–TiO2 and WO3–TiO2 were 75 and 0%, respectively). On the other hand, it was suggested that the interactions between Ce and W ...
