By a News Reporter-Staff News Editor at Science Letter -- Current study results on Phenothiazines have been published. According to news reporting originating in Tehran, Iran, by NewsRx journalists, research stated, "In this paper, Ag/TiO2/beta-cyclodextrin (beta-CD) nano composite was successfully synthesized as a novel friendly nano photo catalyst with ability of loading various compounds. The influence of different beta-cyclodextrin content in the formation of nano composites was investigated."
The news reporters obtained a quote from the research from the University of Tehran, "Various analysis including FTIR, dynamic light scattering (DLS), diffuse reflectance spectroscopy (DRS), XRD, FESEM, EDAX, and TEM were used to characterize the prepared nano composites. The presence of beta-CD in the nano composite was confirmed by FTIR patterns. FE-SEM pictures indicated roughly spherical particles and DLS results showed the average hydrodynamic diameters of 95 nm in aqueous dispersion that was bigger with more beta-CD. TEM images confirmed the presence of three compounds in the nano composites. The peak intensity and the spectra intensity in the visible region increased with more beta-CD confirming synthesis of more Ag on TiO2. The effective role of beta-CD as stabilizer was also proved by the low reduction of the peak intensity for various nano composites after 15 days. One factor response surface methodology (RSM) was applied to model Methylene Blue degradation rate by Ag/TiO2/beta-CD under UV irradiation. The mathematical model suggested significant improvement in the photo degradation rate of Ag/TiO2/beta-CD in comparing with Ag/TiO2."
According to the news reporters, the research concluded: "However, more beta-CD limitedly improved the degradation rate of Methylen Blue and excess beta-CD was detrimental on the reduction of photo degradation rate."
