Reports Outline Nanoparticles Study Findings from Babes-Bolyai University (Structural investigations of TiO2-WO3-Au porous composites)

September 12, 2014

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Nanoparticles have been published. According to news reporting out of Cluj Napoca, Romania, by NewsRx editors, research stated, "In the present study, a morpho-structural analysis of heat treated TiO2-WO3-Au aerogel composites is presented. Simultaneously, the influence of the loaded Au nanoparticles on the morphological and structural characteristics of the TiO2-WO3 aerogel is also analyzed."

Our news journalists obtained a quote from the research from Babes-Bolyai University, "X-ray diffraction data (XRD) and Raman spectroscopy measurements indicated that TiO2 crystallizes mainly in anatase phase, while the WO3 structure remains amorphous. The morphological features of the samples, i.e. crystallites mean size, particle size distribution, and specific surface area of the pores, are investigated by using XRD, transmission electron microscopy (TEM), and N-2 adsorption/desorption, respectively. The results indicate a decrease in size of the titania crystallites as the tungsten oxide content increases."

According to the news editors, the research concluded: "The diffuse reflectance spectra modified by applying a Kubelka-Munk transformation reveal that the presence of gold nanoparticles improves the material's response in the visible domain."
