제목 Iso-layered Sodium Managanese Sulfides Aerogel Formation by Transition Metal Coordination Transformation for Radionuclides Remediation
초록 The aerogels are well explored for oxides with low density, high porosity that build interconnecting structures consisting of random pore sizes. In addition, the sol-gel synthesis of chalcogel is so important to provide the powerful and general approach for the creation of porous nanoarchitecture, namely hydrolysis, condensation, and metathesis reactions. Among these, the metathesis reaction included soluble chalcogenide clusters and linking metal ions is a new method to be able to extend the novel aerogel materials. Here, we report the synthesis Sodium Manganese Sulfide Chalcogels (NMSC) from the anionic chalcogenide cluster is tin sulfide [Sn2S6]4- and manganese ion at several molar ratios. The three-dimension solid network is formed after self-assembly crosslinking at room temperature by metathesis reaction. Additionally, NMSC aerogel can be obtained from the wet gels after supercritical drying, which shows radionuclides remediation ability with the rapid ion uptake.
