Surfactant-assisted synthesis and electrochemical properties of an unprecedented polyoxometalate-based metal–organic nanocaged framework

Abstract

The first polyoxometalate-based nanocaged three-dimensional metal–organic framework was synthesized by a surfactant-assisted hydrothermal method.

A Copper-Containing Polyoxometalate-Based Metal–Organic Framework as an Efficient Catalyst for Selective Catalytic Oxidation of Alkylbenzenes

“…Herein, the introduction of copper atoms is significant from the viewpoint of both catalytic effect and synthesis strategies. In addition, considering that the precise choices of bridging organic ligands may help us to obtain the desired framework, which have satisfactory size, channel, and so on, the logical choice and design of organic ligands are crucial. ,− Owing to its diverse coordination modes (Scheme ), 1,2,4-triazole (trz), as a tridentate ligand, has recently attracted increasing attention in synthetic chemistry. ,− Besides, as the most stable and available POMs, Keggin-type POMs have a quasi-spherical architecture and plenty of surface oxygen atoms, which have been widely studied. ,,− …”

Two Polyoxometalate‐Based Hybrid Compounds Modified by Iron Schiff Base Complexes: Syntheses, Crystal structures, Cyclic Voltametric Studies and Nonlinear Optical Properties

“…[15][16][17] So as to develop organic-inorganic hybrids from a single architecture to functional materials, a rational and cautious selection of organic ligands is crucial. [15,[18][19][20] It is noteworthy that Schiff-base species possess diverse O and N coordination sites, which may be a good candidate for organic ligands. [21][22][23] The limited introduction of a Schiff base can obtain novel and multiple inorganic-organic hybrid materials with excellent properties.…”

“…As is well‐known, owing to the superiority of the combination of POMs and organic groups, the design and exploration of polyoxometalates modified by organic units have been one of the important works of investigators committed to the synthesis of POM [15–17] . So as to develop organic‐inorganic hybrids from a single architecture to functional materials, a rational and cautious selection of organic ligands is crucial [15,18–20] . It is noteworthy that Schiff‐base species possess diverse O and N coordination sites, which may be a good candidate for organic ligands [21–23] .…”

Ternary Cross-Vanadium Tetra-Capped POMOFs@PPy/RGO Nanocomposites with Hybrid Battery-Supercapacitor Behavior for Enhancing Lithium Battery Storage

“…However, conventional graphite anode shows low-charge storage capacity and unfavorable rate capability, limiting the energy output of LIBs. Polyoxometalates (POMs) are a subset of a multi-electron redox active system, resulting in their great applications, especially energy storage applications. − More importantly, POMs as electrode materials for LIBs have exhibited excellent structural stability, , compared with other anode materials, such as Fe 2 O 3 , CuO, ZnS, and so forth.. − Moreover, to address the inherent drawbacks of bulk POMs, immobilizing POMs on various porous metal–organic frameworks (MOFs) to fabricate compounds (POMOFs) were successively explored and applied in the energy stroage system. − Unfortunately, their performance such as the limited cycling capacity and inferior rate performance is still not satisfactory due probably to the poor conductivity. As a consequence, the integration of POMOFs with conductive carbonaceous materials (e.g., RGO (reduced graphene oxide), , CNTs (carbon nanotubes), , and KB (ketjenblack carbon)) is a promising and efficient strategy.…”
