Alkali/transition metal decorated borophene in hydrogen storage through adsorption: A review

Alkali/transition metal decorated borophene in hydrogen storage through adsorption: A review


Hydrogen is indeed an exceptional fuel due to its unique properties, including its large energy content by weight, clean burning, and high gross calorific value of141.9 MJ/kg. It can reduce the serious problem of greenhouse gas exudations by substituting fossil fuels. Currently, there exist diverse methods for stockpiling hydrogen with their own merits and demerits. However, an effective approach is incessantly needed, and the wonder material borophene with extraordinary characteristics can provide it. This review informs the utilization of borophene in hydrogen storage through analysis of multiple computational studies on alkali or transition metal-decorated borophene employing density functional theory. It also encompasses the experimental synthesis of borophene and discusses US Department of Energy (DOE) standards and previously used adsorbent materials. Additionally, required improvements for effective hydrogen fuel-based transportation and safety precautions while stockpiling hydrogen are addressed.

Summary for Non-Scientists

Hydrogen is gaining attention as a superb fuel option because it’s lightweightburnscleanly, and has a high energy content (141.9 megajoules per kilogram).It’s seen as a way to cut down on greenhouse gases that come from using fossilfuels. There are various methods to store hydrogen, each with its own pros andcons, but the search for the most effective method is ongoing. Borophene,a material known for its remarkable properties, could be the answer. This review looks at how borophene can be used for hydrogen storage, based on several computer studies that use density functional theory. These studies often involve adding alkali or transition metals to borophene to enhance its storage capabilities. The review also covers how borophene is made in the lab and talks about the standards set by the U.S. Department of Energy for hydrogen storage materials. It compares borophene to other materials that have been used to store hydrogen. Finally, the review discusses what needs to be improved for hydrogen to be used effectively in transportation and what safety measures should be considered when storing hydrogen.
