Layered Perovskite Oxychloride Bi4NbO8Cl: A Stable Visible Light Responsive Photocatalyst for Water Splitting
Hironori Fujito,Hironobu Kunioku,Daichi Kato,Hajime Suzuki,Masanobu Higashi,Hiroshi Kageyama,Ryu Abe +6 more
TL;DR: This study suggests that a family of Sillen-Aurivillius perovskite oxyhalides is a promising system to allow a versatile band level tuning for establishing efficient and stable water-splitting under visible light.
Journal ArticleDOI
Valence Band Engineering of Layered Bismuth Oxyhalides toward Stable Visible-Light Water Splitting: Madelung Site Potential Analysis
Daichi Kato,Kenta Hongo,Ryo Maezono,Masanobu Higashi,Hironobu Kunioku,Masayoshi Yabuuchi,Hajime Suzuki,Hiroyuki Okajima,Chengchao Zhong,Kousuke Nakano,Ryu Abe,Hiroshi Kageyama +11 more
TL;DR: This study suggests that the Madelung analysis enables a prediction and design of the valence band structures of bismuth and other layered oxyhalides and is applicable even to a compound where DFT calculation is difficult to perform.
Journal ArticleDOI
Preparation of 3-D ordered macroporous tungsten oxides and nano-crystalline particulate tungsten oxides using a colloidal crystal template method, and their structural characterization and application as photocatalysts under visible light irradiation
Masahiro Sadakane,Masahiro Sadakane,Keisuke Sasaki,Hironobu Kunioku,Bunsho Ohtani,Ryu Abe,Wataru Ueda +6 more
TL;DR: In this article, a 3D-ordered macroporous (3DOM) tungsten(VI) oxide (WO3) was prepared using a colloidal crystal template method.
Journal ArticleDOI
Preparation of nano-structured crystalline tungsten(vi) oxide and enhanced photocatalytic activity for decomposition of organic compounds under visible light irradiation
TL;DR: Nano-structured crystalline tungsten(vi) oxides (WO(3)) were prepared using a colloidal crystal template method and after platinum loading they show enhanced photocatalytic activity for acetic acid decomposition under visible light.
Journal ArticleDOI
Strong hybridization between Bi-6s and O-2p orbitals in Sillén–Aurivillius perovskite Bi4MO8X (M = Nb, Ta; X = Cl, Br), visible light photocatalysts enabling stable water oxidation
Hironobu Kunioku,Masanobu Higashi,Osamu Tomita,Masayoshi Yabuuchi,Daichi Kato,Hironori Fujito,Hiroshi Kageyama,Ryu Abe +7 more
TL;DR: In this paper, a series of isostructural oxyhalides, Bi4MO8X (M = Nb, Ta; X = Cl, Br), were examined to examine how the cation and anion substitution affects the band structure and the resultant photocatalytic activity.
