The metal-organic framework (MOF)-type MFM-300(Sc) exhibits a combined physisorption and chemisorption capture of HS, leading to a high uptake (16.55 mmol g) associated with high structural stability. The irreversible chemisorbed sulfur species were identified as low-order polysulfide ( = 2) species. The isostructural MFM-300(In) was demonstrated to promote the formation of different polysulfide species, paving the way toward a new methodology to incorporate polysulfides within MOFs for the generation of novel MOF-lithium/sulfur batteries.
金属有机框架（MOF）型MFM-300（Sc）对HS表现出物理吸附和化学吸附相结合的捕获作用，从而实现了高吸附量（16.55 mmol g）以及高结构稳定性。不可逆化学吸附的硫物种被鉴定为低阶多硫化物（ = 2）物种。同构的MFM-300（In）被证明能促进不同多硫化物物种的形成，为一种将多硫化物纳入MOF以制备新型MOF锂硫电池的新方法铺平了道路。
