Advances in metal-organic frameworks for hydrogen storage

Abstract

With the advancement of science and technology and the rapid growth of the population, the global consumption of energy is increasing rapidly. Traditional fossil fuels are non-renewable resources, and their combustion emits large amounts of greenhouse gases, intensifying the pace of global warming. Therefore, people are looking for renewable resources as an alternative. Among them, hydrogen has attracted much attention due to its high energy density, the combustion product of water, and its wide range of sources. However, efficient and safe storage strategies are required to realize the wide application of hydrogen energy. One of the best materials for storing hydrogen at the moment is metal organic frameworks (MOFs), a three-dimensional porous structure material that has drawn interest because of its large surface area, tunability, and recyclability. For this reason, the preparation techniques for MOFs are initially summarized in this article. The fundamentals of MOFs' hydrogen storage were then described, along with the ways in which various circumstances affect how well they store hydrogen. In conclusion, pertinent ideas for modification were put out to enhance their hydrogen storage effectiveness and offer direction for the creation of materials for hydrogen storage.
