质子导电机理研究进展

Research progress on mechanism of proton conduction

质子由于体积小、无电荷等优点使其在电化学、生物、清洁能源等的传递过程中有特殊的优势,然而质子在物质中的转移过程一直不为人所知,增加对质子的迁移过程的认识对研发新产品、了解生命体的运行和开发清洁能源技术有着极其重要的作用.质子因体积小,可穿过不同的结构而导电,此外质子本身不带电子,易溶剂化形成氢键,也可借助氢键传递而导电.关于对质子传输过程的认识,已形成vehicle机理(载体传输传导机理),hopping机理(跳跃-旋转机制)和溶剂化-扩散机理,但是用这些理论来解释质子的迁移过程还存在一些不足.本文中着重介绍了质子经氧空穴、载体、氢键等途径的传送过程,以及常用的质子传递研究方法.

Because of small volume and no electrons,proton transfer has a special advantage inelectrochemistry,biology and clean energy,however,the proton transfer process in the materials has not beenknown.Increasing awareness of proton transfer plays a very important role in new products research,the studyof life operation and the development of clean energy technology.Because of small bulk,proton can easilycross through different structures and result in conduction,what's more,the proton itself lacking electrons iseasy to solvation and conduction can be realized by hydrogen bond transfer.the mechanisms of proton mobility-vehicle mechanism,hopping mechanism and solvation-diffusion mechanism,take advantage of explaining theprocess about the simplest positive ions,but not enough.We particularly introduces the protonic pathways byway of oxygen vacancy,proton carrier,hydrogen bonds and usual methods of researching proton transfer.
