Four People from the Chinese Academy of Sciences Visit TUS through JST's Sakura Science Plan--Joint Research Activities on Photocatalysis Implemented

2017.12.13 Wednesday


For a 21-day period from November 15 to December 5, two faculty members and two graduate students from the Chinese Academy of Sciences stayed at the Photocatalysis International Research Center at the Noda Campus and conducted joint research through support from the Japan-Asia Youth Exchange Program in Science ("Sakura Science Plan") organized by the Japan Science and Technology Agency (JST).

On the first day of their visit to TUS, the visitors toured the Photocatalysis International Research Center and verified the precautions related to experiments. Afterwards, they participated in a lecture on concrete usage of experimental equipment, and discussed experiment policies. Two days later, a luncheon was held to deepen exchanges with President Akira Fujishima and people involved with the Center, along with a group from the Northeast Normal University in China, who were also in Japan at the same time through the Sakura Science Plan.

Starting the next day, each of the students started research using photocatalysis. They cooperated with students from the Photocatalysis International Research Center to actively make approaches towards research activities, such as conducting experiments late into the night, almost until the last trains. Research contents consisted of evaluating NOx gas removal through decomposition using titanium oxide photocatalysis. Photocatalysis was carried out by using titanium oxide manufactured in China and NOx decomposition evaluation equipment compatible with Japanese Industrial Standards owned by the University's Photocatalysis International Research Center. In evaluating NOx decomposition activity, it was found that upon adding calcium carbonate to titanium oxide, the material obtained exhibited superior performance, thus gaining a foothold in future joint research.

On Saturdays, the visitors went to the National Museum of Emerging Science and Innovation (Miraikan) in Odaiba and Tokyo Skytree in Asakusa, and were able to experience opportunities to learn about Japanese science and technology as well as culture. A welcome party was also held for students, and exchanges between Japanese and Chinese students were deepened.

In the second half of the program, the visitors participated in an international symposium (Photocatalysis 2 & SEIMME'23), where there was a lecture by Professor Zhi Jinfang, who was a guest speaker, and presentation of posters by the students. In the poster presentation, Gao Guanyue received the Young Poster Award. Being able to hold exchanges with exceptional students from China, such as those who win awards at academic societies, and absorb new research in a short period of time through implementing this exchange program provided great stimulation. TUS deeply appreciates the JST's Sakura Science Plan, which has created such opportunities for exchange.
