Metal-Organic Frameworks Towards Desulfurization of Fuels

Abstract

Petroleum is an essential source of energy for our daily life. However, crude oil contains various kinds of sulfur-containing compounds that will form sulfur oxides upon combustion and cause severe environmental problems. To reduce the environmental impact of petroleum energy, the desulfurization of fuels is necessary. Metal-organic frameworks (MOFs), an emerging class of porous materials, have shown great potential in a variety of applications. In this review, we summarize the use of MOFs in the desulfurization of fuels. The scope of this review includes MOFs and MOF-derived materials that have been applied in oxidative desulfurization and adsorptive desulfurization processes. We aim to provide an overview of the progress of MOFs in fuel desulfurization as well as shed light on the development of superior MOF-based materials in the field of desulfurization.
