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...
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 ...
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 ...
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:...
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...
