15th Photocatalyst Symposium
On December 2, the 15th Photocatalyst Symposium was held at KSP Hall (Kanagawa Science Park).
Beginning with the greetings of Prof. Akira Fujishima (Kanagawa Academy of Science and Technology), Chairman of the Photofunctional Materials Society, 5 invited lectures, 81 research presentations, 6 sample displays, research on application of photocatalysts and higher activity And so on. Of particular interest is the study of visible light photocatalysts that react to room light, since the announcement of organic matter decomposition by high performance tungsten oxide photocatalysts at the 7th Photocatalyst Research Discussion Meeting (AIST Kazuhiro Sayama) A lot of new research using “tungsten oxide” continued, and the announcements were full of heat. Among them, practical visible light responsive photocatalysts Cu (II) / WO3, Fe (III) / WO3, WC / WO3, design guidelines for highly sensitive visible light responsive photocatalysts (Professor Kazuhito Hashimoto, Univ. Of Tokyo), tungsten oxide based high Development of an active visible light responsive photocatalyst (Hokkaido University Catalytic Chemistry Research Center Dr. Ryu Abe) attracted attention, and at the sample exhibition, Showa Titanium Co., Ltd. announced the production of visible light responsive photocatalysts Cu / TiO2 and Cu / WO3 within the next year Is scheduled to start selling, and it has been difficult for the interior to use UV lamps depending on the situation. However, the tungsten oxide-based visible light photocatalyst is expected to expand the market. However, since tungsten oxide is expensive compared to titanium oxide, there remains concern about supply price.
