Catalytically active silver nanoparticles stabilized on a thiol-functionalized metal–organic framework for an efficient hydrogen evolution reaction

Abstract

A post-synthetic technique, Solvent Assisted Ligand Incorporation (SALI), was used to incorporate thiol-functionalization in the zirconium-based metal-organic framework, NU-1000. This thiol-functionalized MOF has been employed as a support for the...

Silver Nanoparticle-Decorated Defective Zr-Based Metal–Organic Frameworks for Efficient Electrocatalytic Carbon Dioxide Reduction with Ultrahigh Mass Activity

“…In the solvothermal synthesis of UiO-66, 2-mercaptobenzoic acid was introduced as the modulator that competes with the BDC linker to get bound to Zr-oxo clusters leading to the formation of structural defects in MOFs . The same material has been reported in our recent publication .…”

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

“…150 Recently, Mandal and co-workers reported the HER activity (hydrogen evolution reaction) of Au and Ag nanoparticle immobilized thiol NU-1000-SH. 138,139 The composite material Au@NU-1000-SH exhibits an overpotential of 101 mV at a current density of 10 mA cm −2 with a Tafel slope of 44 mV dec −1 . The control experiment explains the importance of specific thiol MOF and Au nanoparticle interaction in the HER experiment, which shows cycling stability up to 36 h. 139 Ag@NU-1000-SH demonstrated an overpotential of 165 mV at a current density of 10 mA cm −2 with a Tafel slope of 53 mA dec −1 .…”

“…12c). 138 Finally, Ag and Au nanoparticles were immobilized in NU-1000-SH to form Ag@ NU-1000-SH and Au@ NU-1000-SH, both of which are efficient catalysts for the hydrogen evolution reaction. 138,139 3.2.3 Synthesis by the mixed linker strategy.…”

A Novel Silver Nanoparticles‐Decorated Metal‐Organic Framework with Rapid and Sustained Antimicrobial Activity against Drug‐Resistant Candida albicans through Synergistic Chemodynamic and Sonodynamic Therapy

“…Recently, AgNPs-decorated MOFs have been utilized in a variety of applications, including the colorimetric detection of hydrogen peroxide or blood glucose, renewable energy production, ultrasensitive monitoring of blood cholesterol, telomerase activity sensing, and styrene removal. [25][26][27][28][29] In this study, we developed a novel nanoplatform MRA that combines the advantages of CDT, SDT, and long-lasting antimicrobial AgNPs. MRA exhibits high antimicrobial efficacy against drug-resistant C. albicans and has great potential in the treatment of antibioticresistant bacterial infections.…”
