Photocatalytic Applications

Nanocomposite ZnO/ZnFe2O4 photocatalysts with different proportions of ZnFe2O4 were synthesized in organic-free media using metal nitric as precursors. The ZnO phase with hexagonal wurtzite structure and low crystallinity of ZnFe2O4 was confirmed using XRD (X-Ray diffraction). Different morphologies of the nanocomposites were obtained ranging from rice grain-like with a porous surface to homogeneous sphere-like nanoparticles as shown in Scanning Electron Microscopy (SEM) and TEM Transmission Electron Microscopy (TEM) studies. Magnetic properties measured by Visible Sampler Magnetometer (VSM) showed diamagnetic and paramagnetic behavior for the nanocomposites. Analysis with Diffuse Reflectance Spectrophotometer (DRS) UV-vis showed an increase the composition of ferrite in composites increasing its ability to absorb visible light. Photocatalytic activities of ZnO/ZnFe2O4 nanocomposites on the degradation of Rhodamine B dye reached 95.6% after 3 h under natural sunlight suggesting their suitability for sunlight driven photocatalytic applications.

First Time

Petalomonas sphagnophila has been found for the first time in Russia from the Shichengskoe raised bog (Vologda Region). Morphology of the species is studied by means of light microscopy and illustrated by original micrographs. The data on its taxonomy, ecology and distribution are given. The name P. sphagnophila was not validly published because no type was indicated in the original publication (Christen, 1962), so we are validating the name by indicating its holotype. P. polytaphrena Skuja, nom. inval. is treated as a synonym of P. sphagnophila. Currently, thirty species of the genus Petalomonas, including P. sphagnophila, are known from Russia.
