Ultrafast reproducible synthesis of a Ag-nanocluster@MOF composite and its superior visible-photocatalytic activity in batch and in continuous flow

Abstract

The (photo)catalytical properties of Metal-Organic Frameworks (MOFs) can be enhanced by postsynthetic inclusion of metallic species in their porosity. Due to their extraordinarily high surface area and well defined porous...

Optimized 3D Reconstruction of Large, Compact Assemblies of Metallic Nanoparticles

“…In this manner, the position and orientation of the building blocks can be determined in a reliable manner. Furthermore, when combined with a fast tilt series acquisition scheme, it may be used for the investigation of beam sensitive materials, such as for example metallic NPs-loaded porous structures used in catalysis …”

Multimode Electron Tomography Sheds Light on Synthesis, Structure, and Properties of Complex Metal‐Based Nanoparticles

“…Core@shell hybrid nanomaterials have grown in popularity due to their diverse and easily tailored properties for catalysis, optics, and biosensing applications, among others. [3,59,60] As an example, the combination of inorganic metal cores such as plasmonic Au or magnetic Fe 2 O 3 NPs coated with porous and biocompatible surfaces such as silica or metal-organic framework (MOF) structures have been used for controlled photothermal or magnetic-hyperthermal drug delivery devices. [61][62][63] The emerging field of complex hard-soft composite nanomaterials such as "high atomic number" metal nanoparticles encapsulated within "low atomic number" silica or MOF shells, represents a considerable challenge for reliable TEM characterization.…”

Trapping a [W10O32]6− Decatungstate Anion in an Ag44 Nanowheel

“…Hence, the integration of Ag 44 shell and [W 10 O 32 ] 6− anions in the same skelecton appears to bring in a synergistic effect in improving the photodegradation performance of MB [43] . Compound 1 possesses excellent photocatalytic activity under the photoactivation by a xenon lamp irradiation, which can be potentially applied in the fields of sewage disposal [44–45] …”

“…[8] Among the POM functionalized silver clusters, isopolymolybdate and its isomers were the most active anion templates in the core-shell silver clusters. [9,[19][20][21] [23] Subsequently, several POM@silver clusters, such as [Ag 42 {Ho(W 5 O 18 ) 2 }( t BuC�C) 28 Cl 4 ]OH, [24] [Ag 70 (PW 9 O 34 ) 2 ( t BuC�C) 44 [25] [Ag 42 (CO 3 ){C�CC-(CH 3 ) 3 } 27 (α-A-SiW 9 Nb 3 O 40 ) 2 ] À , [26] [Ag 41 (α-SiW 10 O 37 )( t BuC�C) 27 (CH 3 CN) 3 ][β-SiW 12 O 40 ], [27] [Ag 72 (EuW 10 O 36 ) 2 ( t BuC�C) 48 Cl 2 ][BF 4 ] 4 , [28] [Ag 90 (SO 4 ) 2 (W 5 O 19 ) 2 ( t BuC 6 H 4 S) 44 (PhCOO) 24 (DMF) 2 (H 2 O) 2 ] • 2PhCOO, [18] {[Ag 67 (PW 9 O 34 ) 2 (p-F-PhS) 36 (DMAc) 2 (CF 3 COO) 6 ]•(CF 3 COO) 7 •(DMAc) x }, [29] [Ag 10 (W 7 O 26 ) 2 Ag 74 S 2 ( i PrS) 40 ( n PrCOO) 18 ] • 2CH 3 OH [30] and {[K(H 2 O) HP 5 W 30 O 110 ]@Ag 43 ( t BuC�C) 29 (CN)(CH 3 CN)(H 2 O)} • 4CH 3 CN [31] have been synthesized. It indicates that isopolytungstate and its isomers as well as heteropolytungstate and its derivatives are also a class of excellent anion templates for building wonderful POM@silver clusters.…”

“…[43] Compound 1 possesses excellent photocatalytic activity under the photoactivation by a xenon lamp irradiation, which can be potentially applied in the fields of sewage disposal. [44][45] The cyclic voltammetry characteristics of 1 were studied in 0.01 M H 2 SO 4 + 0.5 M Na 2 SO 4 aqueous solution. According to Figure S7a, a pair of weak reversible redox peaks of 1 can be observed at À 0.13 V and À 0.09 V with the mean peak potential E 1/2 = (E pa + E pc )/2 being À 0.11 V, which is assigned to Ag 0 /Ag + couples stemming from the peripheral silver(I) shell.…”
