By a News Reporter-Staff News Editor at Science Letter -- Current study results on Stainless Steel have been published. According to news originating from Qingdao, People's Republic of China, by NewsRx correspondents, research stated, "Composite films of TiO2 and graphene (GR) were prepared on 304 stainless steel (304SS) by the sol-gel method and heat treatment. The morphology, crystalline phase, and composition of the GR/TiO2 films were characterized systematically by X-ray diffraction, Raman spectroscopy and scanning electron microscopy, respectively."
Our news journalists obtained a quote from the research from the Ocean University of China, "The photocathodic protection performances of the composite film under illumination and dark conditions in 3.0% NaCl solution were evaluated through the electrochemical measurements. It is indicated that the incorporation of GR in TiO2 film can improve effectively the photocathodic protection effect for 304SS under the UV illumination. Compared to 350 mV of pure TiO2 film, the electrode potentials can be negatively shifted to about -600 mV under UV light irradiation by incorporating GR into TiO2 films. At the same time, a 14-fold photocurrent density can be obtained for the GR/TiO2 film."
According to the news editors, the research concluded: "This indicates that GR can play an excellent enhancing effect on the photogenerated cathodic protection of TiO2 films."
