emission during consumption. In order to solve the freezing problem of water based hydrolysis process, herein, the Pd/C as an efficient and stable catalyst for the methanolysis, ethanolysis, propanolysis and butanolysis of B2pin2 for the generation of hydrogen has been first developed. The large kinetic isotope effect (KIE) of kH/kD = 5.0, D2 formation from CD3OD and in situ tandem reaction have confirmed
氢作为最有前途的候选
化学燃料之一,因其在消费过程中的零排放而备受关注。为了解决
水基
水解过程中的冻结问题,本文首次开发了Pd/C作为一种高效稳定的催化剂,用于B 2 pin 2的
甲醇分解、
乙醇分解、丙分解和丁分解以制氢。k H /k D = 5.0的大动力学同位素效应 (KIE)、CD 3 OD形成D 2和原位串联反应已证实醇是唯一的氢源。有趣的是,这些醇的E a在 H 中的顺序2演化为MeOH(
甲醇,29.57 kJ/mol)< EtOH(乙醇,34.80 kJ/mol)< PrOH(丙醇,39.08 kJ/mol)< n BuOH(正丁醇,41.98 kJ/mol),与这些醇的已知酸度顺序(MeOH > EtOH > PrOH > n BuOH)。
