“…Apart from the open-metal sites, other weak interactions (e.g., hydrogen-bond interaction and pi interaction) can also facilitate the selective adsorption of C 2 H 2 over C 2 H 4 . Recently, Huang et al [43] used low-cost ligands and Ni salts as raw materials and synthesized a stable microporous Ni-MOF(TJE-1). TJE-1 has 1D channels with a pore size of 0.52 × 0.52 nm.…”

The separation of light hydrocarbon compounds is an important process in the chemical industry. Currently, its separation methods mainly include distillation, membrane separation, and physical adsorption. However, these traditional methods or materials have some drawbacks and disadvantages, such as expensive equipment costs and high energy consumption, poor selectivity, low separation ratios, and separation efficiencies. Therefore, it is important to develop novel separation materials for light hydrocarbon separation. As a new type of organic–inorganic hybrid crystalline material, metal–organic frameworks (MOFs) are promising materials for light hydrocarbon separation due to their designability of structure and easy modulation of function. This review provides an overview of recent advances in the design, synthesis, and application of MOFs for light hydrocarbon separation in recent years, with a focus on the separation of alkane, alkene, and alkyne. We discuss strategies for improving the adsorption selectivity and capacity of MOFs, including pore size limitation, physical adsorption, and chemisorption. In addition, we discuss the advantages/disadvantages, challenges, and prospects of MOFs in the separation of light hydrocarbon.
