The aim of this study was to investigate the photocatalytic activity improving of TiO2, Ag-TiO2 as photocatalysts which immobilized on perlite granules to degrade MB from synthetic wastewater under solar light irradiation. The photocatalytic mechanisms induced by solar light responsive Ag-TiO2/perlite composite was also proposed to demonstrate the photodegradation of MB cationic dye.

In this research, Ag-Ag3PO4/Cellulose aerogel composite was synthesized using hydrothermal reduction and freeze-drying methods. By combining the photocatalytic activity of the semiconductor AgAg3PO4 and cellulose aerogel synthesized from agricultural waste sources, the synthesized Ag-Ag3PO4/Cellulose aerogel composite has overcome the disadvantages of pure Ag3PO4 and significantly improved the photocatalytic activity.

In this study, we successfully synthesized a bimetallic metal-organic framework material Zn/Co-ZIF to start Peroxymonosulfate (PMS) for organic dye degradation in the water body. Material characterization was evaluated by advanced methods, such as XRD, FT-IR, SEM, EDX, and BET. The influence of different factors on methylene blue (MB) decomposition rate was investigated.

This article, we present a thorough and straightforward hydrothermal method towards the production of reduced graphene oxide templated MIL-53(Fe) hybrids RGO@MIL-53(Fe). The structural characteristics of created hybrids were identified by using BET, FESEM, powder X-ray diffraction, and FTIR techniques. Methylene blue (MB) dye (a model water pollutant) was used to evaluate H2O2-assisted photo-catalytic efficiency of RGO@MIL-53(Fe).

Optimization techniques predict the conditions required to increase the efficacy of azo dyes degradation by microbial sources and also decrease the number of experimental runs to achieve the maximum percentage of degradation. Interaction of variables such as medium components and process parameters can be determined using optimization tools.

In this paper, oxidation of red methyl (MR) - an azo in dye by UV / H2O2 was studied. The effect of solution volume and initial concentration was studied. Under optimal conditions, project a UV light through the bottom of the solution containing MR. The rate of color change is proportional to the increase of H2O2 concentration. After 50 minutes, the decolorization effect with 16 ppm H2O2 is 38%, slightly higher than the content of 14 ppm H2O2.

The photocatalytic oxidation of reactive blue 2 and reactive red 120 has been studied by using TiO2 Degussa P25 as catalyst and UV-light. The formation of intermediate molecules could be predicted on the basic of point charge calculations on all the individual atoms of the dyes. The agreement between calculations from quantum theory and the results of experiments was the background to establish a pathway for degradation of reactive dyes. A plausible mechanism of dye photodegradations is discussed.
