Molybdenum blue preassembly strategy to design bimetallic Fe_0.54Mo_0.73/Mo₂C@C for tuneable and low-frequency electromagnetic wave absorption

Abstract

Advanced electromagnetic wave absorption nanomaterials can play an important role in addressing the issue of increasing electromagnetic pollution in wireless communication field. Herein, a series of coralloid bimetallic Fe0.54Mo0.73/Mo2C@C (FMC)...

Directional Shunting of Photogenerated Carriers in POM@MOF for Promoting Nitrogen Adsorption and Oxidation

“…[ 43 ] For the XPS spectrum of C 1s, O 1s, and Mo 3d (Figures S16–S18, Supporting Information), new peaks appear in Mo 72 Fe 30 @UiO‐66. [ 44 ] The above results suggest that there is a strong interaction between Mo 72 Fe 30 and UiO‐66 in favor of electron transfer. [ 45 ]…”

[44] The above results suggest that there is a strong interaction between Mo 72 Fe 30 and UiO-66 in favor of electron transfer. [45] In order to verify the charge separation efficiency, electrochemical impedance spectroscopy, time photocurrent curve, photoluminescence (PL) emission spectroscopy, and diffuse reflectance UV-vis spectra were performed.…”

Co‐Ni Electromagnetic Coupling in Hollow Mo2C/NC Sphere for Enhancing Electromagnetic Wave Absorbing Performance†

“…There are multiple valence states of Co and Ni in the samples, including elementary state and oxidation state, both of which have a great contribution to the improvement of magnetic properties of the nanomaterials. [ 60‐61 ]…”

Drawing Inspiration from Nature: Trinitarian Strategies for Designing Polyoxometalates and Metal–Organic Framework-Based Biomimetic Microhoneycomb Electromagnetic Wave-Absorbing Materials

“…The nanometer size of POMs ensures that they can be embedded into the narrow pores of porous materials to form supramolecular assemblies. As an ideal platform for molecular preassembly, POMs can preintroduce various metals with excellent electromagnetic properties into the molecular system during synthesis . As an important subclass of POMs, heteropolyoxometalates introduce additional heteroatoms as variable valence elements, which are beneficial for altering the electron microenvironment .…”

“…As an ideal platform for molecular preassembly, POMs can preintroduce various metals with excellent electromagnetic properties into the molecular system during synthesis. 17 As an important subclass of POMs, heteropolyoxometalates introduce additional heteroatoms as variable valence elements, which are beneficial for altering the electron microenvironment. 18 The introduction of heteroatoms disrupts the regular lattice structure in the POM derivative process, creating local lattice distortions.…”
