A series of iridium-based catalysts for dehydrogenation of formic acid, and hydrogenation using formic acid as the hydrogen source, and the process using the catalyst(s) to produce hydrogen gas from formic acid solution, or to reduce aldehydes using formic acid, are disclosed and claimed. More specifically, the present invention relates to a group of pentamethylcyclopentadienyl (Cp*) iridium complexes with different Ν,Ν-bidentate ligands that catalyze dehydrogenation from formic acid, and chemo-selective hydrogenation of aldehydes, in the aqueous solution system in a highly efficient, and long life-time manner.
本发明公开并申请了一系列基于铱的催化剂,用于甲酸的脱氢以及使用甲酸作为氢源的加氢反应,以及使用该催化剂从甲酸溶液中产生氢气,或使用甲酸还原醛的过程。更具体地说,本发明涉及一组具有不同Ν,Ν-双齿配体的五甲基环戊二烯基(Cp*)铱络合物,它们在水溶液体系中以高效和长寿命的方式催化甲酸的脱氢和醛的选择性加氢。
