The degradation of rhodamine B

In this study, we report on the hydrothermal synthesis of ZnO nanorods and the change in photocatalytic properties with different hydrothermal temperatures in the decomposition of Methylene blue (MB) and Rhodamine B (RhB) under visible light.

The Mn-doped MoS2 (Mn-MoS2) material is fabricated by a facile onestep calcination method. The Mn2+ content introduced into MoS2 is ranged from 1 wt% to 7 wt%. The X-ray diffraction (XRD) and scanning electron microscopy SEM results suggest that the doping of Mn2+ does not alter the crystal structure and the morphology of MoS2.

In this study, the photocatalytic degradation of rhodamine b (RhB) is investigated over metal-organic framework materials based on bismuth and trimesic acid (Bi-BTC) with different metal-to-ligand molar ratios. All obtained products are characterized by using powder X-ray diffraction, scanning electron microscopy, and UV–vis diffuse reflectance spectroscopy.

TiO2-Graphene Oxide-Hemin (TiO2/GO/Hemin) ternary composite hybrid material was prepared by the sol-gel method and used as a heterogeneous catalyst for the photocatalytic degradation of organic contaminants. The catalytic activity of GO-TiO2-Hemin was evaluated by the degradation of Rhodamine B (RhB) under the UV-visible light irradiation and in the presence of hydrogen peroxide.

The sepiolite support possesses fibrous structure. X-ray diffraction analysis pointed out that the TiO2 particles are firmly distributed on fibrous sepiolite matrix. All TiO2/sepiolite samples were tested for the degradation of rhodamine B and showed a high catalytic activity. The experimental data showed that the degradation efficiency of rhodamine B is correlated with the amount of TiO2 loadings and oxidant behavior. At room temperature, the conversion of rhodamine B reaches to 99-100 % over 6.0 wt% TiO2/sepiolite catalyst.
