Partially Reversible H 2 S Adsorption by MFM-300(Sc): Formation of Polysulfides

The metal-organic framework (MOF)-type MFM-300(Sc) exhibits a combined physisorption and chemisorption capture of H S, 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) speci...

Description
Summary:The metal-organic framework (MOF)-type MFM-300(Sc) exhibits a combined physisorption and chemisorption capture of H S, 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.
