“…Electrochemical measurements were taken using a conventional three-electrode configuration with an as-prepared brookite TiO 2 /FTO employed as the working electrode (1 cm × 1 cm), a Pt wire as the counter electrode, and a Ag/AgCl electrode as the reference. The working electrode of TiO 2 /FTO was prepared according to the method reported in our previous work [24]. The electrodes were placed 3 cm apart, and the supporting electrolyte was 0.1 mol/L Na 2 SO 4 solution.…”

Brookite TiO 2 , the latest TiO 2 photocatalyst, promises to be an interesting candidate for photocatalytic applications because of its unique physical and chemical properties. In this study, pure-phase brookite TiO 2 with a quasi-spherical nanostructure was successfully synthesized via a solvothermal method using tetrabutyl titanate (Ti(OC 4 H 9 ) 4 , TBOT) as the Ti source in the presence of oxalic acid. NaOH was used to regulate the pH of solution. The structure and morphology of the samples were then analyzed using multiple methods, such as X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET) measurements and ultraviolet-visible diffuse spectroscopy (UV-Vis). Photocatalytic activities of the as-synthesized brookite TiO 2 were evaluated by degrading aqueous methylene blue solution under UV light irradiation. The effect of thermal treatment temperature on photocatalytic activity of the samples was also investigated. The produced brookite TiO 2 nanopowders calcined at 500 °C for 2 h showed the highest photocatalytic activity, and the corresponding degradation rate of methylene blue (10 mg/L) reached 96.7% after 90 min of illumination. In addition, the formation mechanism of pure-phase brookite TiO 2 was investigated. It was found that the formation of pure-phase brookite TiO 2 in this study was ascribed to the combined action of oxalic acid and sodium hydroxide.

“…As for the traditional photocatalytic degradation of VOCs, the utilization efficiency of solar energy is very low. Though some studies have extended the photoresponse of various photocatalysts from ultraviolet to visible light or even infrared region by decorating modification, the efficiency is still low [84,[87][88][89][90]. Photo-thermocatalytic oxidation, which combines the excellent catalytic efficiency and excellent durability of thermocatalytic oxidation with low energy consumption of photocatalytic oxidation, has become a very effective method for reducing air pollutants.…”

With the development of industrialization, the emission of volatile organic compounds (VOCs) to atmosphere causes serious environmental problems and the treatment of VOCs needs to consume a lot of energy. Moreover, indoor VOCs are seriously harmful to human health. Thus, there is an urgent requirement for the development of indoor VOCs treatment technologies. Catalytic degradation of VOCs, as a low energy consumption, high efficiency, and easy to achieve manner, has been widely studied in related fields. As a kind of transition metal catalyst, manganese-based catalysts have attracted a lot of attention in the catalytic degradation of VOCs because of their unique advantages including high efficiency, low cost, and excellent stability. This paper reviews the state-of-the-art progress of manganese-based catalysts for VOCs catalytic degradation. We introduce the thermocatalytic, photocatalytic and photo-thermocatalytic degradation of VOCs on manganese-based catalysts in this paper. The optimization of manganese-based catalysts by means of structural design, decorating modification and defect engineering is discussed. Graphical Abstract
