摘要
利用自动反应路径搜索法研究了 C3H8 在 TiH2 表面脱氢和随后偏合成的反应机理。预测的路径表明,脱氢反应可能发生在 TiH2 表面的 H 空位处。初始脱氢反应形成的亚丙基物种是丁烷形成的关键中间体;而金属氢化物表面上的后续偏合成反应又需要这种化合物。
Reaction path search for propane dehydrogenation and metathesis on titanium hydride
The reaction mechanisms of C3H8 dehydrogenation and subsequent metathesis on a TiH2 surface were investigated using an automated reaction path search method. The predicted pathway suggests that dehydrogenation could occur at the H vacancies present on the TiH2 surface. The propylidene species formed by the initial dehydrogenation reaction are crucial intermediates in butane formation; this compound is in turn required by the subsequent metathesis reaction on the surface of the metal hydrides.
