One-pot synthesis of sulfonic acid functionalized Zr-MOFs for rapid and specific removal of radioactive Ba²⁺

Abstract

Efficient decontamination of radioactive Ba2+ is of great significance to human health and environmental safety. Herein, an adsorbent of sulfonic acid functionalized Zr-MOF has been successfully developed, which could efficiently...

Nanoporous Sulfonic Covalent Organic Frameworks for Selective Adsorption and Separation of Lanthanide Elements

“…As shown in Figure c, the binding energy of O 1s increased significantly after adsorption, which can be attributed to the ion exchange between the proton and La 3+ and the formation of the new chemical bonds (O-La). The S 2p XPS spectrum of TFPB-DABDA iCOFs further proves the occurrence of ion exchange (Figure d). ,, These results are also consistent with the kinetic and adsorption isotherm fitting results, indicating that the adsorption process of TFPB-DABDA iCOFs is mainly dominated by chemical adsorption and belongs to monolayer adsorption.…”

Enhanced early‐stage adsorption of chemical warfare agent simulant by MIL‐68‐(X%OH)

“…[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] Among these, MOFs are the most promising materials due to their unique ability to customize their chemical and physical properties for specific applications. [30][31][32][33][34][35][36][37][38][39][40][41][42][43] The careful selection of organic linkers is especially important in determining the distinctive properties of an MOF. A wide range of organic linkers has been developed to create MOFs with precisely tailored properties.…”

“…A wide range of organic linkers has been developed to create MOFs with precisely tailored properties. [34][35][36][37][38][39][40][41][42][43] Notably, the presence of dangling functional groups within the MOF structure can facilitate specific interactions with guest molecules during adsorption or reaction processes within the MOF framework. [39][40][41][42][43] In this study, we present MOF-based adsorbents designed to efficiently capture the CWA simulant, particularly in the early stages of exposure.…”

As a representative system for investigating the adsorption of 2-chloroethyl ethyl sulfide (CEES), we have chosen MIL-68, which boasts a highly porous structure with a robust Kagomé pattern.…”

Enhance Hydrogen Isotopes Separation by Alkali Earth Metal Dopant in Metal–Organic Framework

“…Alkali earth metal dopants in MOF materials have experimentally realized but mostly focused on Mg, Ca, and Ba, − but Be as a dopant in MOFs was only theoretically studied without the experimental support because its stronger covalency than other alkali earth metals lead to the difficulty of Be dopant experimentally . Therefore, the dopant of +2 alkali earth metal ions into MOF materials can be basically realized by experiments.…”
