SPE水电解催化剂研究进展

Progress of SPE water electrolysis catalyst technology

作为一种高效的制氢技术,固体聚合物(SPE)水电解技术受到越来越多的研究人员的关注与研究。介绍了最近几年内SPE水电解技术在析氢、析氧催化剂、催化剂载体及催化剂制备工艺等方面的研究进展。指出目前限制SPE技术商业化的关键仍是催化剂成本过高和活性不强,因此未来研究的重点应当是高性能二元或多元催化剂和耐腐蚀催化剂载体的制备。

As a high efficient hydrogen production technology, the solid polymer electrolysis （SPE） water electrolysis technology has attracted more and more researchers＇ attention. In this paper, SPE water electrolysis technologies were reviewed in catalyst for hydrogen evolution and oxygen evolution, catalyst support and catalyst preparation research progress and development direction. It is pointed out that the key to limit the SPE technology commercialization is still the high cost and the low catalyst activity. Therefore, future research should focus on low-cost high-performance binary or multicomponent catalyst and corrosion resistant catalyst carrier preparation.
