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.

甲烷和乙炔代表更清洁的燃料，被认为是化石燃料的理想替代品。由于在环境条件下体积能量密度低，因此非常需要开发多孔材料，例如金属有机骨架，相对于它们，它们表现出良好的吸附性能。在这篇综述中，我们首先介绍了用于乙炔和甲烷存储的多孔金属有机框架的设计和合成的发展历史，并分析了一些代表性的例子。然后我们重点讨论了它们的吸附机理，包括气体结合位点和气体-骨架相互作用。最后，总结了一些结构—性质关系和合成策略，以改善它们的气体吸附性能。
