The mechanism in the CF3C1-H2-O2 reaction and the rate constant k2 at high temperature were reported. When 0.1 percent CF3C1 was added to the mixture (4 percent H2, 2 percent O2, and 94 percent Ar), the induction period (the elapsed time between reflected shock arrival and onset of ...
近日,中科院大连化学物理研究所的李灿院士(通讯作者)课题组在Angew. Chem. Int. Ed.上发文,题为“Photoassisted Oxygen Reduction Reaction in H2–O2 Fuel Cells”。该研究小组提出ORR活性在聚噻吩(pTTh)电极照射时大大增强。 起始电势从0.66正向偏移到1.34V,电流在0.6V下增加了44倍。一种概念验证的光驱动H2-O2...
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 ...
同时,还释放出一定量的能量,这是一种受控释放的热能反应,换句话 说,是水热反应(water-thermal reaction)。 二、还原反应: 在点燃 H2 和 O2 反应之后,也会发生一种叫做还原反应的反应,也就是 O2 + 2e - → 2O2-。在还原反应中,氧分子会被电子还原,产生氧离子,即氧化还原号从 0 变为-2, 此时,还会有...
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:...
By probing low pressure flames of H2-O2-N2-N2O, and using the ratios of rate constants previously determined in flames, we find that the rate constant for the reaction of oxygen atoms with hydrogen molecules is 2.5 ± 0.4 × 108 l.. mole-1 sec.-1 at 1660°K. and 3.0 ± 0.3 × 10...

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 ...
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 ...
