A thiol-containing zirconium MOF functionalized with silver nanoparticles for synergistic CO₂ cycloaddition reactions

Abstract

Thiol-containing biomolecules, such as cysteine and glutathione, have essential roles in regulating the polarity and reactivity of the systems. Among functional MOFs, thiol MOF, a subclass with a thiol group-containing...

Thiol and thioether-based metal–organic frameworks: synthesis, structure, and multifaceted applications

“…The valuable applications of Zr-DMBD are due to this free-standing thiol group; since it is very reactive and easily functionalizable, there are numerous opportunities for post-synthetic modifications for specific applications. 97–107 All reported post-synthetic modifications of Zr-DMBD for their significant applications are listed in Table 4. Compounds derived from Zr-DMBD via post-synthetic methods have extensive use spanning multiple domains.…”

“…Ag@Zr-DMBD acts as an efficient catalyst with synergistic usage of the Zr and Ag centre for CO 2 fixation by converting the terminal epoxide to corresponding cyclic carbonates in ambient conditions. 103 Ag@MOF-s-SH (Table 9, entry no. 9) synthesized by Liu et al also acts as an efficient catalyst for CO 2 fixation reactions.…”

Silver Nanoparticle-Functionalized Postsynthetically Modified Thiol MOF UiO-66-NH-SH for Efficient CO2 Fixation

“…In MOF synthesis, linkers with common functional groups, like alkyl (–R), amines (–NH 2 ), − alcohols (–OH), , and halide (–X), , have been utilized frequently. In the functional MOFs category, thiol MOFs acquire a unique space because of the electronically soft nature of the thiol group, which can bring specific advantages to the MOFs like high reactivity and selectivity toward soft metal ions like Ag, Pd, Au, etc. − …”

“…In 2013, Xu and co-workers reported a benchmark thiol MOF Zr-DMBD by the solvothermal reactions between 2,5-dimercaptoterephthalic acid (H 2 DMBD) and ZrCl 4 . 38 The thiol MOF (Zr-DMBD) containing free-standing thiol groups are utilized over the year in different applications like heavy metal adsorption, 46 photocatalysis, 47 heterogeneous catalysis, 39,48 other thiol functional ligands, like 3,3′-dimercapto-1,1′biphenyl-4,4′-dicarboxylic acid (H 2 DMBPD), 49 4,4′,4″,4′″-(pyrene-1,3,6,8-tetrayl)tetrakis(2,6-dimercaptobenzoic acid) (H 4 OMTP), 50 etc., are also utilized for synthesizing thiolbased MOFs. However, the scarcity of thiol-based ligands and synthetic difficulties such as multistep synthesis, high-temperature requirements, air sensitivity, instability, and propensity toward oxidation make it challenging.…”

Coordinatively unsaturated 5-nitroisophthalate based cobalt(ii) coordination polymers: efficient catalytic CO2 fixation and Hantzsch condensation

“…4 As the world strives to transition entirely to renewable and clean energy sources, the capture and chemical conversion of CO 2 into valueadded products emerges as an effective green approach. [5][6][7][8][9] Current methods, like amine scrubbing, face challenges, including high pressure, high energy consumption, and heavy instrumentation. 10 An attractive alternative lies in harnessing the non-toxic and abundant CO 2 as a versatile C1 source for producing cyclic carbonates (CCs).…”
