A team under Ajou's Professor In Sun Cho develops nano material technology that raises efficiency of hydrogen production2015-09-15A team led by Ajou University's Professor In Sun Cho (Department of Materials Science and Engineering, pictured above) developed nano material manufacturing technology that will significantly raise the efficiency of hydrogen production through solar cells.The research was conducted with the support for essential research projects carried out by the National Research Foundation of Korea, and its findings were published in the August 18th issue of The Nano Letters, a renowned academic journal in the field of nano-technology, under the title of "Highly Efficient Solar Water Splitting from Transferred TiO2 Nanotube Arrays."Professor Cho said that he joined hands with Professor Jong Hyeok Park (Yonsei University) and Professor Tai Ho Park (Pohang University of Science and Technology) to develop nano material manufacturing technology that will significantly raise sunlight absorption and electricity conductivity by using TiO2, a photocatalyst.The research will increase the efficiency of hydrogen production through solar-cell-based water splitting to the highest theoretical level. The technology allows for hydrogen production by splitting water with semi-conductor materials and solar cells. While hydrogen energy is drawing attention as a clean energy of the future, the technological production efficiency should be at least 10 percent for it to be commercialized.However, there has been difficulty in raising hydrogen production efficiency via solar cells, because titanium oxide (TiO2), tungsten oxide (WO), or bismuth vanadium oxide (BiVO), that are used as an oxidation photoelectrode have low efficiency.In order to address this issue, the research team created titanium oxide nanotube material by making a nanotube structure from titanium oxide material and applying dual reduction procedures that combine chemical and flame reductions.Professor Cho said, "The highly efficient nano material technology based on chemical and flame reductions can be applied to tungsten oxide, iron oxide, and bismuth vanadium oxide, etc. as well as those based on titanium oxide," adding, "These materials are very high in theoretical efficiency levels, and I believe that the 10 percent efficiency limit can be surpassed through additional research and development.The research by Professor Cho's team can expand applications of titanium oxide materials that are being used in many products including cosmetics and paint. In addition, the findings are expected to considerably increase the chances of commercializing solar-cell-based hydrogen reduction technology. The commercialization is predicted to come within the next ten years. < Diagram of titanium oxide transfer coating on nanotube, and the technological process of chemical and flame reductions >

A research team led by Ajou University’s Professor Dong Il Yeom (Department of Physics, Graduate School’s Department of Energy System Research, pictured above) has developed graphene-optical fiber devices available for electrical control for the first time in the world. Graphene, a single atomic layer that combines carbon atoms in a beehive shape, is drawing attention as a “new dream material” since its high conductivity, transparency, and flexibility allow for the production of next-generation electric devices, photoelectric devices, and optical devices such as semiconductors, displays, and solar cells. However, it has been difficult to make optical devices and photoelectric devices with highly efficient photoreaction capacities from the single-layer graphene because its light absorbing rate is around a mere 2.3%. The research team led by Professor Yeom developed the world’s first graphene-optical fiber photoelectric devices by combining Field Effect Transistor (FET) and optical fiber, which has previously been difficult due to technological limitations. The team also succeeded in developing an ultra-short pulse optical fiber laser that can be electrically controlled via photoelectric devices. FET is called a unipolar transistor because only single polarity electrons are involved in the electricity conduction within semi-conductors. The photoelectric device developed by the research team is highly efficient, allowing for adjusting the light absorption rate up to 90% through interactions between graphene and the damped wave (evanescent wave) generated by the light moving along optical fiber. Professor Yeom said, “The graphene-optical fiber photoelectric device our team has developed can be directly applied to the optical fiber laser that is now being used in precise laser processing for industrial uses or in building laser-enabled weapons. I expect that the device can also contribute to developing photoelectronic or optical devices based on highly efficient graphene.” The research findings were published in the April 2015 issue of Nature Communications, a world-class science journal (Impact Factor over the past 5 years: 11.023), with the title of “Active Control of All-fiber Graphene Devices with Electrical Gating.” Eun Jeong Lee (graduate from the University’s master’s course), Seon Yeong Choi (postdoctoral course), and Hwan Seong Jeong (combined master’s/PhD program) took part in the research as first authors, and Professor Fabian Rotermund (co-corresponding author), Professor Ji Yong Park, Professor Yeong Hwan Ahn, and Professor Gwang Jun Ahn collaborated with the research team. The study was conducted with the support for basic research projects carried out by the Ministry of Science, ICT and Future Planning and the National Research Foundation of Korea.
