Catalytic Decomposition of H2O(D2O) on a Heated Ir Filament to Produce O and OH(OD) Radicals

Autor: Hiroki Kusanagi, Hironobu Umemoto

Publikováno v: Open Chemical Physics Journal. 2(1):32-36

Production of O atoms, H(D) atoms, and OH(OD) radicals was confirmed in the catalytic decomposition of H2O(D2O) on a heated Ir filament by laser spectroscopic techniques, such as vacuum-ultraviolet laser-induced fluorescence. The highest steady-state

ChemInform Abstract: Mechanism for Photodecomposition of 4,8,10-Trithiadibenzo(cd,ij) azulene 8-Oxides

Autor: Naomichi Furukawa, Hiroki Kusanagi, Takayoshi Fujii

Publikováno v: ChemInform. 27

4,8,10-Trithiadibenzo[cd,ij]azulene 8-oxides were prepared and their photolysis provided a convenient procedure to yield the corresponding aldehydes and ketones together with 4,8,9-trithiacyclopenta[def]phenanthrene.

Catalytic decomposition of O2, NO, N2O and NO2 on a heated Ir filament to produce atomic oxygen

Autor: Hiroki Kusanagi, Hironobu Umemoto

Publikováno v: Journal of physics. D, Applied physics. 41(22):225505-225505

Production of O atoms was confirmed in the catalytic decomposition of O2, NO, N2O and NO2 on a heated Ir filament. No change in electric resistivity was observed when the filament was kept at 2350 K in the presence of 0.8 Pa of these species, showing
