Journal ArticleDOI
In situ ambient pressure XPS study of CO oxidation reaction on Pd(111) surfaces
Ryo Toyoshima,Masaaki Yoshida,Yuji Monya,Yuka Kousa,Kazuma Suzuki,Hitoshi Abe,Bongjin Simon Mun,Bongjin Simon Mun,Kazuhiko Mase,Kenta Amemiya,Hiroshi Kondoh +10 more
TL;DR: In this article, the CO oxidation reaction on the Pd(111) model catalyst at various temperatures (200 −400 °C) under hundreds mTorr pressure conditions has been monitored by in situ ambient pressure X-ray photoelectron spectroscopy.
Journal ArticleDOI
Control of the interchain π-π interaction and electron density distribution at the surface of conjugated poly(3-hexylthiophene) thin films
TL;DR: It can be deduced that the slower removal rate of the solvent makes the polymer chains even at the surface have sufficient time to adopt a more nearly equilibrium structure with edge-on conformation, which buries the pi-electron density contributed from the polymer backbone.
Journal ArticleDOI
Adsorbate-driven reactive interfacial Pt-NiO1−x nanostructure formation on the Pt3Ni(111) alloy surface
Jeongjin Kim,Woong Hyeon Park,Won Hui Doh,Si Woo Lee,Myung Cheol Noh,Jean Jacques Gallet,Fabrice Bournel,Hiroshi Kondoh,Kazuhiko Mase,Yousung Jung,Bongjin Simon Mun,Jeong Young Park +11 more
TL;DR: It is shown that the inherent lattice mismatch of bimetallic materials selectively creates surface segregation of subsurface metal atoms, which is responsible for a highly efficient step in the CO oxidation reaction.
Journal ArticleDOI
Epitaxial Rh-doped SrTiO3 thin film photocathode for water splitting under visible light irradiation
Seiji Kawasaki,Kan Nakatsuji,Jun Yoshinobu,Fumio Komori,Ryota Takahashi,Mikk Lippmaa,Kazuhiko Mase,Akihiko Kudo +7 more
TL;DR: In this article, the valence of the Rh dopant in the rh:SrTiO3 films was found to have a p-type behavior under visible light irradiation, reproducing the known optical absorption behavior of powder samples.
Journal ArticleDOI
Active Surface Oxygen for Catalytic CO Oxidation on Pd(100) Proceeding under Near Ambient Pressure Conditions.
Ryo Toyoshima,Masaaki Yoshida,Yuji Monya,Kazuma Suzuki,Bongjin Simon Mun,Kenta Amemiya,Kazuhiko Mase,Hiroshi Kondoh +7 more
TL;DR: In-situ observation of the reaction reveals that two reaction pathways switch over alternatively depending on the surface temperature, which is likely that the enhanced rate of CO2 formation is associated with an active oxygen species that is located at the surface of the trilayer oxide.
