Associate Professor / Nobuo SAITO
Associate professor Saito is a friendly teacher. So, we feel free to discuss about research with him. In addition, he has a wealth knowledge about analytical equipment. He teaches us how to use it and some measurement principles.

Research Content

Our research theme is to develop new photocatalysts. It is one of approach to solve energy issues and environmental problems. Photocatalyst can convert photoenergy to chemical energy by some chemical reaction on its surface due to production of electron and hole generated by light irradiation. We have investigated about improvement of photocatalytic activity, response for visible light or elucidation of reaction mechanism. And, our main themes are “H2 production by water splitting”, “Removal of heavy metal in water” and “Organic compound decomposition”.

A Day in the Lab

We have weekly seminars to report about our research and introduce an English paper. In these seminars, we discuss about them with assoc.prof.Saito and laboratory members. Our laboratory has a core time, 9:00am to 4:30pm on Monday to Friday. So we should come laboratory and work by ourself. On the other hand, we can enjoy student lifes and some events with laboratory members such as “Cherry-blossom viewing party” and “Nagaoka Fireworks”. In addition, we often accept some exchange students. So we have many opportunities to spend time with them.
