Textile industry stands out as it produces a large amount of coloured dye effluents which are toxic and biodegradables. Among the different types of dyes used textile industry, 60-70% is azo compound. An extensive research on photocatalysis of TiO2 has attracted significant attention for solving these problems due to its high potential for ensuring the complete destruction of organic compound in the...
In this abstract, a significantly efficient modification method for Sm2Ti2S2O5 was introduced by employing both reduction and oxidation cocatalysts to improve the H2 activity from water. The modified photocatalyst Sm2Ti2S2O5 is loaded with Ag2S and Rh.The preparation of Ag2S/Sm2Ti2S2O5 involves a one-pot synthesis of by sulfurizing a mixed oxide consisting of Ag, Sm, and Ti, followed by deposition...
Phase-pure anatase TiO2 nanocrystals with a tunable crystallinity have been prepared by a one-step solvothermal method in the absence of any templates or additives. 2-Propanol, which has the lowest dielectric constant of those studied, favors the crystallization of TiO2 nanocrystals with the best crystallinity, and highest photocatalytic efficiency. The effect of the dielectric constant on the processes...
Photocatalytic oxidative kinetics of thiophene in n-octane/water extraction system was studied with nano-TiO2 powders as photocatalyst and O2 in air as oxidant. Influence of initial concentration of thiophene and addition of TiO2 on reaction rate constant and half time were investigated. Kinetics equation was founded. The results showed that the approviate addition of TiO2 was 0.1 g in 100 mL reaction...
High-performance TiO2 photocatalysts have been mainly issued in the area of photoactive materials for a long time. The role of anatase-rutile phase boundary on the photoactivity of TiO2 could be demonstrated combining the materials data with NEXAFS results. An interface between anatase and rutile phases (phase boundary) was directly proved to trap the electrons excited from the valance band, for the...
