The dye-pigments and organic compounds are known as significant pollutants in wastewater of textile industrial. Among of treatment technologies, the photocatalysis using TiO2 nano particles has potential on-site process for removing the dye-pigments and organic compounds, due to no hazardous waste and inexpensive. In this work, the TiO2 nanoparticles were synthesized by two different methods of hydrothermal and sol-gel. Nanoparticle of TiO2 synthesized by hydrothermal method contained pure anatase phase as similar as the TiO2 nanoparticles synthesized by sol-gel method. However, the TiO2 synthesized by hydrothermal method provided the higher specific surface area and pore volume rather than the another TiO2. Further, the high efficiency 86% of methylene blue photodegradation was observed during the by using TiO2 synthesized by hydrothermal method as photocatalyst, whereas the efficiency was only 72% for TiO2 synthesized by sol-gel method.

In this work, La0.5Sr0.5CoO3 (LSCO) perovskite oxide with perfect crystallinity was successfully synthesized via a sol–gel method and then used as counter electrodes (CEs) for dye-sensitized solar cells (DSSCs). The DSSCs with LSCO CEs exhibited excellent electrocatalytic activity for the triiodide reduction and yielded a power conversion efficiency of 7.17%, which is greater than that of the Pt electrode (7.06%). Compared with the hydrothermal method and solvothermal method, sol–gel method is more suitable for large scale preparation. This work should open up a new class of CE materials for low-cost and high-efficiency DSSCs.

Elemental mercury (Hg0) emitted from a coal-fired boiler is a serious menace and challenge to humans. Using high-efficiency CeO2/TiO2 catalysts to enhance the conversion from elemental mercury to oxidized mercury is a promising approach to reducing Hg0 emission. However, most of the CeO2/TiO2 catalysts were prepared by impregnation method or coprecipitation method while little attention has been paid to sol–gel method, which has many advantages in material production. In this study, a series of catalysts were synthesized through the sol–gel method to remove the gaseous Hg0 from simulated flue gas. The effect of vanadium (V) on Hg0 removal efficiency and the simultaneous removal of Hg0 and NO were also investigated. The results showed the optimal temperature for Hg0 removal over the CeO2/TiO2 catalysts was 350 °C. The oxidation of Hg0 could be promoted by O2, HCl, and NO, but inhibited by NH3 and SO2. The addition of vanadium could enhance the Hg0 removal performance and the resistance to NH3 and SO2. A synergetic effect was found during the simultaneous removal of Hg0 and NO. The high redox reaction reactivity of Ce4+/Ce3+ and V5+/V4+ should take the credit for the oxidation of Hg0 and the removal of NO. Based upon the performance tests and the characterization experiments of the samples, the detailed mechanisms of the Hg0 and NO removal over the catalysts were proposed.
