Kenichi Honda

Kenichi Honda (本多健一, August 23, 1925 – February 26, 2011) was a Japanese chemist. He made a significant contribution to the discovery and characterization of photocatalytic properties of titanium dioxide (TiO2), for which he shared the 2004 Japan Prize with his former student Akira Fujishima.[1]

Biography

In 1949 Honda received his bachelor's degree in engineering from the University of Tokyo. He then spent several years in France, where he defended a PhD in 1957 at the University of Paris. After returning to Japan he obtained a second doctorate degree, from the University of Tokyo in 1961. He then worked as a lecturer (1965–1975) and professor (1975–1983) at the University of Tokyo and at Kyoto University (1983–1989).[2] In 1989 he moved to the Tokyo Polytechnic University and served as its president in 1996–2004.[1]

Research

In the late 1960s Honda and his doctorate student Akira Fujishima discovered the Honda-Fujishima effect - photocatalytic water decomposition (photolysis) upon exposing a titanium dioxide electrode to strong light. For this discovery, published in 1972,[3][4] Honda and Fujishima received the 2004 Japan Prize.[1]

gollark: Specifically, you said "if it doesn't involve running a different language it's probably fine".
gollark: Wait, does this imply I can't ship osmarkslisp™?
gollark: I think it's meant to be like the ML-style `(*` comments, but arbitrarily different.
gollark: Thanks!
gollark: It's certainly possible.
