Porous metal-organic frameworks for fuel storage

Methane and acetylene represent cleaner fuels, which are considered as ideal alternatives to fossil fuels. Due to low volumetric energy density at ambient conditions, it is highly desirable to develop porous materials such as metal-organic frameworks that exhibit good adsorption properties with respect to them. In this review, we firstly introduced the development history on the design and synthesis of porous metal-organic frameworks for acetylene and methane storage in which some representative examples were analyzed; and then we focused on discussing their adsorption mechanisms including the gas binding sites and gas-framework interactions. At last, some structure-property relationships and synthetic strategies for improving gas adsorption properties with respect to them were summarized. (C) 2017 Elsevier B.V. All rights reserved.
