Research Progress in Methane Storage Using the Metal-Organic Frameworks

Abstract

The improvement of social production and social technology in recent times has led to a gradual increase in the worldwide energy demand. In addition to the issue of shortage, burning fossil fuels like traditional oil produces a significant quantity of greenhouse emissions, which contribute to global climate change. In today's world, natural gas is an essential clean energy source. These days, liquefied natural gas (LNG), adsorbed natural gas (ANG), and compressed natural gas (CNG) are the most widely utilized storage techniques. ANG is the most promising method since it offers advantages over other approaches, including room temperature storage, safety, dependability, efficiency, and environmental protection. The most popular adsorbent materials at the moment are metal-organic frameworks (MOFs), which are characterized by a high specific surface area and porosity, a topological structure and pore size that can be adjusted, strong solvent stability, and heat stability. For this reason, the structural traits and techniques of the production of MOFs are first summarized in this article. The methane adsorption process was then clarified. Ultimately, the use of MOFs in methane storage was highlighted to offer some guidance for the advancement of MOFs as adsorbent materials in the future.
