Low-dimensional structure compounds as layered perovskite shows high photocatalytic activity in water splitting. In this study, we investigated that synthesis and characterization of photocatalytic activity of BaGeGa6O12 with a one-dimensional structure. BaGeGa6O12 with loading 0.3wt% RuO2 showed a photocatalytic activity for water splitting into H2 (70.6 μ mol / h) and O2 (28.1 μ mol / h).

Monoclinic scheelite BiVO4 was synthesized from a mixture of aqueous Bi(NO3)3 and NH4VO3 solutions by hydrothermal method. Then using successive coating of BiVO4 with a carbon layer and a ZrO2 layer followed by heat treatment to remove the carbon layer prepared a core-shell(ZrO2@void@BiVO4) nanoparticles with a void layer between the BiVO4 core and the ZrO2 shell. TG-DTA and IR suggest that BiVO4 was coated with ZrO2. TEM shows that there was a void space between the BiVO4 core and the ZrO2 shell. The samples were characterized by XRD and the peaks of ZrO2@void@BiVO4 suits well with the pure phase monoclinic scheelite BiVO4. And its visble-light photocatalytic activity was evaluated by the photodegradation of methylene blue(MB). The results indicated that the photocatalytic activity of ZrO2@void@BiVO4 is similar to that of pure phase BiVO4, which makes it can be used for preparing liquid-gas phase boundary visble-light photocatalyst.

Degradation Of Dyes

Graphene oxide/Cuprous oxide (GO/Cu2O) composite is a visible light photocatalyst for the degradation of dyes. A simple and efficient approach for preparing GO/Cu2O composite adopted in this study involves reducing cuprous oxide precursors in the presence of graphene oxide using an aqueous solution of pulp derived from banana fruit. The GO/Cu2O composite was characterized by Fourier transform infrared spectroscopy (FT-IR), Diffused reflectance Ultraviolet visible spectroscopy (DRS UV-Vis), Raman spectroscopy and Field Emission Scanning electron microscopy (FE-SEM). Cu2O particles were distributed randomly on the graphene oxide sheets due to the template effect of GO. The results showed higher photocatalytic activity for the composite (band gap 2.13 eV), for the degradation of the organic dyes (Methylene blue and Rhodamine-B). The enhanced photocatalytic activity is due to effective charge transfer from GO to Cu2O, and high specific surface area which improves the effective separation of the generated electron–hole pairs. Our present study is inspired by a facile, low cost, green production of (GO/Cu2O) composite whose photocatalytic activity can be extended to degradation of all other water-born textile dyes.

Anodization Method

An anodized TiO2 membrane has enhanced photocatalytic properties of anatase phase and small crystal size. From the photocatalytic results, the prepared anodized nano-structured TiO2 membrane had an effective organics decomposition capacity and high water permeability. This anodization method enabled the prepared nano-structured TiO2 membrane to have high photocatalytic activity and desired pore structure.
