摘要: Heterogeneous ignition temperature of H2/O2/N2 mixture on polycrystalline platinum was measured for a wide range of composition at 101,330 Pa. We propose a new surface kinetic model of H2 oxidation on platinum by modification of the traditional surface reaction model.关键词:...
The H2/O2 reaction on a polycrystalline palladium foil has been studied. The experimental methods used were Laser-Induced Fluorescence (LIF) and microcalorimetry. The reaction was also simulated with the Chemkin software package. The water production maximum occurs at 40% H2 and the OH desorption ...
Energy partitioning in the reaction 2H2+ O2→ 2H2O on Pd(111) We have studied the reaction on Pd(111) at temperatures between 500 and 700 K in the regime of low oxygen coverages ( 2. D2 is dosed using a ... Arne de Meijere,Kurt W. Kolasinski,Eckart Hasselbrink - 《Faraday ...

Arrhenius parameters for the reaction C2H5+ O2→ C2H4+ HO2 Studies have been made of the relative yields of C2H4 and C2H6 produced in the oxidation of propionaldehyde over the temperature range 593–753 K and the r... Kevin G. McAdam,Raymond W. Walker - 《Journal of the Chemical Society...
O2, H2 and H2O have been adsorbed in the dark and the decrease on the concentration of the Ti3+ species has been monitored as a function of the gas exposures. Subsequent band gap illumination partially restores the Ti3+ initial concentration in the cases of O2 and H2 exposures but not in ...
In [3] a kinetic modeling of the H2/O2 reaction on a polycrystalline palladium surface was done. This model is of a modified Langmuir-Hinshelwood type and it takes into account the possibility that hydrogen may ab- sorb on the interface sites. The simulations were done in the temperature ...
H2 + Br2 = 2HBr Suggest two reasons why all the collisions between hydrogen and bromine gas molecules do not result in a reaction. Compare the boiling points of 1-hexanol and hexanal. Explain their difference. For the following pair, choose the member with the lower boiling point and explain...
