Polyoxometalate-based metal–organic complexes constructed from a new bis-pyrimidine-amide ligand with high capacitance performance and selectivity for the detection of Cr(VI)

Emulsion‐assisted interfacial polymerization strategy: Controllable architectural engineering of anisotropic and isotropic nanoparticles for high‐performance supercapacitors

“…The galvanostatic charge/discharge (GC) tests of NPCPs samples were conducted at different current densities from 0.1 to 5 A g −1 (Figures 4B and Supporting Information: Figure S12b,d). The smooth curves exhibit a typical triangular shape and are almost symmetric, which visually demonstrates the ideal double‐layer capacitance behaviors as well as the reversibility 35–37 . The GC curves of different NPCPs samples at the constant current density of 0.2 A g −1 are shown in Figure 4C.…”

“…The smooth curves exhibit a typical triangular shape and are almost symmetric, which visually demonstrates the ideal double-layer capacitance behaviors as well as the reversibility. [35][36][37] The GC of different NPCPs samples at the constant current density of 0.2 A g −1 are shown in Figure 4C. NPCPs-0.4 possessing abundant microporous structure, plentiful nitrogen content and a hollow single-cavity morphology conducive to mass transfer, thus, exhibits the longest discharging time and the highest specific capacitance (275 F g −1 ) at 0.2 A g −1 , which is consistent well with the results of the CV tests.…”

Nanomaterial with Core–Shell Structure Composed of {P2W18O62} and Cobalt Homobenzotrizoate for Supercapacitors and H2O2-Sensing Applications

“…The sensitivity was 8.65 mA mM −1 cm −2 and the total linear range was 1.9 μM~1.67 mM, superior to literature reports [ 76 , 77 , 78 , 79 ]. The linear range may be due to the large specific surface area and porosity of the POMOF core–shell structure, which facilitates the homogeneous dispersion of precursors and the transfer of electrons to the internal structure, thereby improving the reaction kinetics on the surface of the electrode material [ 80 ].…”

A hybrid borotungstate-coated metal–organic framework with supercapacitance, photocatalytic dye degradation and H2O2 sensing properties

“…70 OH ad is combined with Ag-BTC, 52 with a large specific surface area and uniform distribution. The mechanism of the sensor is summarized based on the literature [82][83][84] as follows:…”
