水分解制氢以其巨大的应用前景备受人们青睐。实现H＋的产生过程和H＋与电子结合过程的分离是提高水分解制氢效率的关键步骤。基于过渡金属催化氧化环戊二烯扩环反应,研究了Fe（Ⅲ）/环戊二烯反应体系催化水分子中的H＋与OH-的分离过程,实现了H＋的分离。厌氧和无水实验证明副产物吡喃盐化合物中的氧来源于水分子,且只有在水存在条件下反应体系pH值才下降,从而证实了H＋源于水的分解,借助氢离子半透膜装置,实现了与OH-的分离。检测到三价铁盐催化剂可借助于空气中氧气的氧化作用,实现不断地重复催化氧化分解水的过程,说明Fe（Ⅲ）/环戊二烯反应体系是一种有效分解水的体系。

As one of the most important research focus,hydrogen production by water decomposition have received considerable attentions in recent decades whereas encountering the bottleneck of low decomposition efficient,which were caused by the recombination of freed H＋ and electrons.Making separation of two processes of H＋ generation and combination of H＋ and electrons separating is a useful work as well as a challenge.Based on our previous work of transition metal assisted ring-expanding reaction of cyclopentadienes,herein a system of Fe（Ⅲ）/cyclopentadiene assisted water decomposition was developed to independently produce H＋.The water decomposition process was demonstrated by aqueous-free experiment with inhibitive reaction,and the H＋ production was clarified by lower pH value.The cyclic experiment of water decomposing has been illustrated,indicating Fe（Ⅲ）/cyclopentadiene is excellent system for decomposition of water.
