Journal ArticleDOI
GaN:ZnO Solid Solution as a Photocatalyst for Visible-Light-Driven Overall Water Splitting
Kazuhiko Maeda,Tsuyoshi Takata,Michikazu Hara,Nobuo Saito,Yasunobu Inoue,Hisayoshi Kobayashi,Kazunari Domen +6 more
TL;DR: This is the first example of achieving overall water splitting by a photocatalyst with a band gap in the visible light region, which opens the possibility of new non-oxide-type photocatalysts for energy conversion.
Journal ArticleDOI
Ammonia synthesis using a stable electride as an electron donor and reversible hydrogen store
Masaaki Kitano,Yasunori Inoue,Youhei Yamazaki,Fumitaka Hayashi,Shinji Kanbara,Satoru Matsuishi,Toshiharu Yokoyama,Sung Wng Kim,Sung Wng Kim,Michikazu Hara,Hideo Hosono +10 more
TL;DR: Kinetic analysis with infrared spectroscopy reveals that C12A7:e(-) markedly enhances N(2) dissociation on Ru by the back donation of electrons and that the poisoning of ruthenium surfaces by hydrogen adatoms can be suppressed effectively because of the ability of C12 a7: e(-) to store hydrogen reversibly.
Journal ArticleDOI
Hydrolysis of Cellulose by Amorphous Carbon Bearing SO3H, COOH, and OH Groups
Satoshi Suganuma,Kiyotaka Nakajima,Masaaki Kitano,Daizo Yamaguchi,Hideki Kato,Shigenobu Hayashi,Michikazu Hara +6 more
TL;DR: The carbon catalyst can be readily separated from the saccharide solution after reaction for reuse in the reaction without loss of activity, and the catalytic performance of the carbon catalyst is attributed to the ability of the material to adsorb beta-1,4 glucan, which does not adsorb to other solid acids.
Journal ArticleDOI
Conduction and Valence Band Positions of Ta2O5, TaON, and Ta3N5 by UPS and Electrochemical Methods
Wang-Jae Chun,Akio Ishikawa,H. Fujisawa,Tsuyoshi Takata,Junko N. Kondo,Michikazu Hara,Maki Kawai,Yasumichi Matsumoto,Kazunari Domen +8 more
TL;DR: In this article, the conduction and valence band edges for electronic band gaps and Fermi levels are determined for Ta2O5, TaON, and Ta3N5 by ultraviolet photoelectron spectroscopy (UPS) and electrochemical analyses.
Journal ArticleDOI
Oxysulfide Sm2Ti2S2O5 as a Stable Photocatalyst for Water Oxidation and Reduction under Visible Light Irradiation (λ ≤ 650 nm)
Akio Ishikawa,Tsuyoshi Takata,Junko N. Kondo,Michikazu Hara,Hisayoshi Kobayashi,Kazunari Domen +5 more
TL;DR: In this article, a Ti-based oxysulfide, Sm(2,Ti(2)S(2),O(5), was studied as a visible light-driven photocatalyst.
