1. Comprehensive study combining surface science and real catalyst for NO direct decomposition

Author:
Masaaki Haneda; Yoshiaki Kintaichi; Isao Nakamura; Tadahiro Fujitani; Hideaki Hamada
Source:
Chemical communications 2002 v. no.23 pp. 2816-2817
ISSN:
1364-548X
Subject:
aluminum oxide; catalysts; catalytic activity; chemical reactions; models; nitric oxide; palladium
Abstract:
... The catalytic activity of Pd/Al₂O₃ prepared from various palladium precursors for direct NO decomposition is closely related to the fraction of surface step sites capable of dissociating NO, on the basis of a surface science study using single-crystal model catalyst. ...

2. Interplay of anions and ligands on the nature and reducibility of NiOₓ/Al₂O₃ catalysts prepared by impregnation

Author:
F. Negrier; E. Marceau; M. Che
Source:
Chemical communications 2002 v. no.11 pp. 1194-1195
ISSN:
1364-548X
Subject:
aluminum oxide; anions; catalysts; chemical reactions; chlorides; heat treatment; ligands; nickel; nitrates; nitrogen; temperature
Abstract:
... When NiOₓ/Al₂O₃ catalysts (Ni wt% = 1.5) are prepared by impregnation using [NiL₂(H₂O)₂]X₂ as precursors (L = diamine, X = Cl⁻ or NO₃⁻), a supported oxidic or metallic phase can be selectively obtained after thermal treatment in N₂ depending on the nature of the ligand and counter anion ; the oxidic phase can be reduced at a lower temperature than the classical nickel aluminate phase obtained from ...

3. New carbon nanofiber/graphite felt composite for use as a catalyst support for hydrazine catalytic decomposition

Author:
R. Vieira; C. Pham-Huu; N. Keller; M. J. Ledoux
Source:
Chemical communications 2002 v. no.9 pp. 954-955
ISSN:
1364-548X
Subject:
aluminum oxide; carbon nanofibers; catalysts; catalytic activity; chemical reactions; graphene; hydrazine; iridium; mechanical properties; surface area; thermal conductivity
Abstract:
... Graphite felt supporting 40 nm diameter carbon nanofibers was synthezised and successfully used as a support for a high loaded iridium catalyst (30 wt%) in the decomposition of hydrazine; a strong mechanical resistance and a high thermal conductivity led to a very efficient and stable catalyst as compared to that used industrially, iridium supported on a high surface area alumina. ...

4. Susceptibility of a heterogeneous catalyst, Rh/γ-alumina, to rapid structural change by exposure to NO

Author:
Tom Campbell; Andrew J. Dent; Sofia Diaz-Moreno; John Evans; Steven G. Fiddy; Mark A. Newton; Sandra Turin
Source:
Chemical communications 2002 v. no.4 pp. 304-305
ISSN:
1364-548X
Subject:
aluminum oxide; catalysts; chemical reactions; heat production; nitric oxide; particle size; rhodium
Abstract:
... Metal particles in a Rh/γ-Al₂O₃ catalyst of differing particle size are oxidised by NO/He within 5 seconds at 313 K; rapid, highly exothermic dissociative chemisorption of NO is the initial step. ...

Source:
Chemical communications 2002 v. no.3 pp. 288-289
ISSN:
1364-548X
Subject:
aluminum oxide; catalysts; catalytic activity; chemical reactions; hydrazine; iridium; molybdenum
Abstract:
... An alumina-supported Mo₂C catalyst is found to be as active as a conventionally used Ir/γ-Al₂O₃ catalyst for catalytic decomposition of hydrazine tested in a monopropellant thruster. ...
