Supported Anionic Gold Nanoparticle Catalysts Modified Using Highly Negatively Charged Multivacant Polyoxometalates

Abstract: Although supported anionic gold nanoparticle catalysts have been theoretically investigated for their efficacy in activating O 2 in aerobic oxidation reactions, limited studies have been reported due to the difficulty of designing these catalysts. Herein, we developed a feasible method for preparing supported anionic gold nanoparticle catalysts using multivacant lacunary polyoxometalates with high negative charges. We confirmed the strong and robust electronic interaction between gold nanoparticles and multiva… Show more

“…The advancement in nanoscience has brought much excitement to the material science field since nanomaterial scientists are capable of precisely controlling the physical‐chemical properties at the atomic level to yield advanced materials with extraordinary performances [1, 2] . Among these nanomaterials, the research of metal nanoclusters in the ultrasmall size regime (<2 nm of the metallic kernel) has been one of the increasing worldwide interests [3–15] . Metal nanoclusters feature quantum size effects and discrete electronic energy levels, rendering them prominent nanomaterials for in‐depth structure‐property studies with applications in catalysis, chemical sensing, bioimaging, and nanomedicine [16–23] .…”

“…On the other hand, the suitable combination of AuNPs with POMs could integrate the plasma-enhanced effect for synergistic catalysis. 30 Compared to spherical AuNPs, elongated AuNRs absorb NIR light, which make them an excellent plasma photothermal agent. Thus, the combination of POMs with AuNRs could be expected to achieve the property of plasma-enhanced photothermal catalysis.…”

“…[8] Moreover, highly negatively charged POMsupported gold nanoparticles exhibit better catalytic activity and stability than the conventional gold nanoparticle catalysts. [9] This has been assigned to the robust electronic interactions between polyoxometalates and gold nanoparticles. Over the last few years, the development of POMs in the field of biomedicine has been of particular interest.…”

“…It is assumed that POM acts as electron reservoir for modulating the surrounding electronic environment of the catalytic active site. [8,9] Intriguingly, the consumption of bacterial H 2 S is beneficial to disrupt biofilm formation, suppress bacterial tolerance and reduce the number of persisterbacteria (persisters). [37,38] Taking advantage of the improved catalytic performance, acid-responsive assembly and reduction-response photothermal absorption behavior of POMs, this is an elegant strategy to exploit POMs for pathology-specific therapy and improved treatment efficacy.…”
