Data from Jozef Stefan Institute Provide New Insights into Nanowires

February 10, 2014

By a News Reporter-Staff News Editor at Nanotechnology Business Journal -- Current study results on Nanowires have been published. According to news reporting originating from Ljubljana, Slovenia, by VerticalNews correspondents, research stated, "We report a new flame reduction method to generate controllable amount of oxygen vacancies in TiO2 nanowires that leads to nearly three times improvement in the photoelectrochemical (PEC) water-splitting performance."

Our news editors obtained a quote from the research from Jozef Stefan Institute, "The flame reduction method has unique advantages of a high temperature (>1000 degrees C), ultrafast heating rate, tunable reduction environment, and open-atmosphere operation, so it enables rapid formation of oxygen vacancies (less than one minute) without damaging the nanowire morphology and crystallinity and is even applicable to various metal oxides."

According to the news editors, the research concluded: "Significantly, we show that flame reduction greatly improves the saturation photocurrent densities of TiO2 nanowires (2.7 times higher), alpha-Fe2O3 nanowires (9.4 times higher), ZnO nanowires (2.0 times higher), and BiVO4 thin film (4.3 times higher) in comparison to untreated control samples for PEC. water-splitting applications."
