As a clean and ideal energy source, hydrogen energy has received extensive attention in recent years. However, the technology for hydrogen storage is still the key technology restricting the application of hydrogen commercialization. Hydrogen storage materials are considered to be safe, efficient way for solid-state hydrogen storage. Therefore, the development of new high-capacity hydrogen storage materials and hydrogen storage technology is one of the hot topics nowadays. Nanoconfinement is to fill the materials in the nanopores. By using the interaction between the filled materials and nanopore, the reaction is promoted. In recent years, nanoconfinement has become an effective way to enhance the kinetics and thermodynamics of the hydrogen storage materials. In this paper, the development of nanoconfined hydrogen storage materials has been reviewed. The preparation, hydrogen storage properties, reaction mechanism and existing problems for nanoconfined hydrogen storage materials are discussed. In addition, the future prospect of nanoconfined hydrogen storage materials is addressed. Contents
