Size-Matching and Soft-Base Synergy: A 3D Supertetrahedral Cluster Based Oxysulfide Open Framework for Exceptional Sr 2+ Adsorption

Key Points

• The central aim is to develop and analyze a new open framework that effectively adsorbs Sr2+ ions.
• Developed a supertetrahedral cluster-based open framework for ion exchange.
• Examined the framework's capabilities for Sr2+ adsorption against competing ions.
• Analyzed the synergistic effects of size-matching and soft-base interactions.
• The framework exhibited significantly higher Sr2+ adsorption compared to other competing ions.
• Demonstrated effective ion exchange properties with a high capacity for Sr2+ uptake.
