Journal ArticleDOI
Gold Nanoparticles Located at the Interface of Anatase/Rutile TiO2 Particles as Active Plasmonic Photocatalysts for Aerobic Oxidation
Daijiro Tsukamoto,Yasuhiro Shiraishi,Yoshitsune Sugano,Satoshi Ichikawa,Shunsuke Tanaka,Takayuki Hirai +5 more
TL;DR: This plasmonic photocatalysis is successfully promoted by sunlight exposure and enables efficient and selective aerobic oxidation of alcohols at ambient temperature.
Journal ArticleDOI
Highly Selective Production of Hydrogen Peroxide on Graphitic Carbon Nitride (g-C3N4) Photocatalyst Activated by Visible Light
Yasuhiro Shiraishi,Shunsuke Kanazawa,Yoshitsune Sugano,Daijiro Tsukamoto,Hirokatsu Sakamoto,Satoshi Ichikawa,Takayuki Hirai +6 more
TL;DR: In this article, the authors showed that visible light irradiation of graphitic carbon nitride (g-C3N4), a polymeric semiconductor, in an alcohol/water mixture with O2 efficiently produces H2O2 with very high selectivity (∼90%).
Journal ArticleDOI
Au/TiO2 Nanosized Samples: A Catalytic, TEM, and FTIR Study of the Effect of Calcination Temperature on the CO Oxidation
Flora Boccuzzi,Anna Chiorino,Maela Manzoli,Ping Lu,Tomoki Akita,Satoshi Ichikawa,Masatake Haruta +6 more
TL;DR: In this paper, three Au/TiO 2 catalysts, with the same Au loading and with different particle sizes, were prepared by the deposition-precipitation method followed by calcination at three different temperatures, 473, 573, and 873 K. The mean diameters of Au particles were 2.4, 2.5, and 10.6 nm, respectively.
Journal ArticleDOI
Sunlight-Driven Hydrogen Peroxide Production from Water and Molecular Oxygen by Metal-Free Photocatalysts†
Yasuhiro Shiraishi,Shunsuke Kanazawa,Yusuke Kofuji,Hirokatsu Sakamoto,Satoshi Ichikawa,Shunsuke Tanaka,Takayuki Hirai +6 more
TL;DR: A photocatalytic process for H2 O2 synthesis driven by metal-free catalysts with earth-abundant water and molecular oxygen (O2 ) as resources under sunlight irradiation (λ>400 nm).
Journal ArticleDOI
Photocatalytic H2O2 Production from Ethanol/O2 System Using TiO2 Loaded with Au–Ag Bimetallic Alloy Nanoparticles
Daijiro Tsukamoto,Akimitsu Shiro,Yasuhiro Shiraishi,Yoshitsune Sugano,Satoshi Ichikawa,Shunsuke Tanaka,Takayuki Hirai +6 more
TL;DR: In this paper, the double effects created by the alloy particles were investigated, namely photocatalytic reduction of O2 on the Au atoms promoting enhanced H2O2 formation, due to the efficient separation of photo-formed electron-hole pairs at the alloy/TiO2 heterojunction.
