New Photoelectrochemicals Study Findings Recently Were Reported by N. Sobti and Co-Researchers (Structural and photoelectrochemical properties of porous TiO2 nanofibers decorated with Fe2O3 by sol-flame)

By a News Reporter-Staff News Editor at Biotech Week -- Researchers detail new data in Biotechnology. According to news reporting out of Constantine, Algeria, by NewsRx editors, research stated, "The hybrid structure of Fe2O3 nanoparticles/TiO2 nanofibers (NFs), combines the merits of large surface areas of TiO2 NFs and absorption in ultraviolet light-visible light range. This structure can be used for many applications such as photoelectrochemical water splitting and photo-catalysis."

Our news journalists obtained a quote from the research, "Here, a sol-flame method is used for depositing Fe2O3 on TiO2 NFs that were prepared by hydrothermal on Ti sheets. The obtained materials were characterized by XRD, SEM, UV/Vis diffuse reflectance, Raman, and XPS. The results revealed the formation of rutile and anatase crystalline phases together with Fe2O3. This process moves the absorption threshold of TiO2 NFs support into visible spectrum range and enhances the photocurrent in comparison to bare TiO2 NFs, although no hole scavenger was used. The impedance measurement at low and high frequencies revealed an increase in series resistance and a decrease in resistance of charge transfer with sol-flame treatment time."

According to the news editors, the research concluded: "A mechanism for explaining the charge transfer in these TiO2 NFs decorated with Fe2O3 nanoparticles was proposed."
