Direct sulfhydryl ligand derived UiO-66 for the removal of aqueous mercury and its subsequent application as a catalyst for transfer vinylation

Abstract

The treatment of mercury pollutants in water has been widely concerned. Adsorption is a promising method for mercury removal that has been extensively studied. Nevertheless, the secondary application of the...

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

“…17g). 102 The stability of sulfenyl iodides (RS-I) is environment-dependent, making them an interesting family of compounds. In the solution phase, it is precarious for its disproportionation tendency (2RS-I → RSSR + I 2 ).…”

“…The valuable applications of Zr-DMBD are due to this freestanding thiol group; since it is very reactive and easily functionalizable, there are numerous opportunities for post-synthetic modifications for specific applications. [97][98][99][100][101][102][103][104][105][106][107] All reported postsynthetic 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.…”

“…190 MOFs have been utilized extensively for heavy metal adsorption. Notably, thiol and thioether-based MOFs exhibit significant utility in this domain 136 (d) hydrogenolysis of biomass-derived aromatic aldehydes, 134 (e) CO 2 fixation reaction by Ag@ Zr-DMBD, 103 (f ) Ag@UiO-66-catalysed A 3 coupling reaction, 141 (g) Zr-DMBD-Hg as a vinyl transfer reaction, 102 (h) Suzuki Miyaura reaction (SMR) by Zr-DMTD-Pd and UiO-67-(SH) 2 -Pd catalyst, 67,113 (i) conversion of alkynes by hydroalkoxylation. 92…”

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

“…Many studies have used Zr-DMBD as a Hg adsorbent due to the propensity of the free thiol group to form a covalent bond with electronically soft mercury ions. 32,45 Xu and co workers have demonstrated the application of Zr-DMBD for efficient Hg adsorption. 32 In 2018, Sun and coworkers studied the Hg adsorption mechanism of Zr-DMBD.…”

Co-adsorption and Fenton-like oxidation in the efficient removal of methylene blue by MIL-88B@UiO-66 nanoflowers

“…Water pollution has brought serious threats to organisms and ecological systems. [1][2][3] Each year, the textile industry worldwide discharges >5000 tonnes of organic dyes into water, most of which are highly toxic (and even carcinogenic) to organisms. Organic dyes are usually composed of aromatic rings, which exhibit good structural stability and cannot undergo biodegradation readily.…”
