Tentative title
Novel Insights of Heterogeneous Photocatalysis to Go Beyond Band-structure Model
 
The research work on photocatalysis by Professor Ohtani started in 1981 when he was a Ph. D. course student in Kyoto University.  Since then he has been studying photocatalysis and related topics for more than 30 years and published more than 290 original papers (h-index: 67) and two single-author books.  After gaining his Ph. D. degree from Kyoto University in 1985, he became an assistant professor in the university.  In 1996, he was promoted to an associate professor in Division of Chemistry, Graduate School of Science, Hokkaido University and was then awarded a full professor position in the Catalysis Research Center (presently Institute for Catalysis), Hokkaido University in 1998.  For the education of graduate students, Professor Ohtani's laboratory has belonged to the Graduate School of Environmental Science, Hokkaido University since 1999.  He was awarded 2005 Scientific Achievement Award of The Electrochemical Society of Japan, The Japanese Photochemistry Association Award 2006, Catalysis Society of Japan Award for 2013, The Japanese Photochemistry Association Lectureship Award (2017) and The Award of The Electrochemical Society of Japan (Takei Award), 2018.
