Recent advances of two-dimensional metal-organic frameworks in alkaline electrolysis water for hydrogen production

Hydrogen evolution production via electrolysis of water in alkaline solution is a promising mean of industrial hydrogen production. However, inefficiency and high cost restrict its industrialization development. Based on extensive studies of experimental and theoretical investigations, two-dimensional (2D) materials are promising substitute of noble metals for hydrogen evolution reaction (HER) with low cost and high-efficiency. Herein, recent progress in 2D metal-organic frameworks (MOFs) for HER in alkaline electrolyte is systematically discussed and summarized. This review describes the strategies about how to design and optimize the structure of 2D MOF-based materials as HER electrocatalysts with well performance and aims to provide potential avenues for industrial hydrogen production. Additionally, the challenges and future directions ahead in this field are also proposed.
