Reaction mechanismsHigh reactivity of rare earths (RE) with H2, O2 and H2O is well known even at room temperature. The formation of stable surface oxides/hydroxides on the surface is the one of serious problems in the production and use of materials containing RE. We have investigated the ...
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...
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...

Profile measurements of the H2/O2 reaction have been obtained using a variable pressure flow reactor over pressure and temperature ranges of 0.3–15.7 atm and 850–1040 K, respectively. These data span the explosion limit behavior of the system and place significant emphasis on HO2 and H2O2 kine...
实验结果表明:烟煤焦在 CO2、H2O和 O2多组分混合气氛下的反应结果与基于共用活性位假设的L-H动力学模型的预测趋势比较吻合;对于单组份气氛,Char-O2、Char-H2O和Char-CO2的反应速率由快到慢排序为:rChar-O2rChar-H2OrChar-CO2,其中rChar-O2比rChar-H2O高出一个数量级,rChar-H2O约是rChar-CO2的六倍至八...
