The State and Prospects of Porous Coordination Polymers as Hydrogen Storage Materials at Cryogenic Temperature and Room Temperature

Abstract

Abstract: As one of the promising H₂ storage materials, porous coordination polymers (PCPs), also known as metal-organic frameworks (MOFs), have been extensively studied for the past decade. PCPs are crystalline materials constructed by metal ions and organic linkers to have micropores. We overview PCPs that have been developed for H₂ storage materials to summarize their structures, organic linkers, and physical properties. The big issue is the gap of H₂ storage capacity between at cryogenic temperature and room temperature. Furthermore, we describe the prospects of PCPs as H₂ storage material.
