Abstract:

Water splitting, metal-air batteries and fuel cells are energy conversion technologies that are critical to solving future energy crises and environmental problems. The oxygen reduction reaction(ORR), oxygen release reaction(OER) and hydrogen release reaction(HER), as the core reactions, have the problem of slow kinetic speed, so it is of great significance to develop efficient non-noble metal electrocatalysts. Metal-organic frameworks(MOFs) have attracted more and more attention in different applications due to their highly tunable compositions and porous crystal structures. And hollow MOFs have the advantages of highly adjustable composition and structure of MOFs, as well as the advantages of hollow structure nanomaterials, such as faster transmission quality, more abundant porosity, rich active components, more exposed active sites, and better compatibility with harsh conditions, etc., and show great potential applications in the field of electricity catalysis. In this paper, the preparation of hollow MOFs based structural materials and their research progress in electrocatalysis in recent years are reviewed, and the challenges and prospects in this field are summarized.

Key words: Hollow structure, Metal-organic framework, Synthesis strategy, Electrocatalysis
