Facile synthesis of ZIF-67 derived dodecahedral C/NiCO₂S₄ with broadband microwave absorption performance

Abstract

The increasing hazard of electromagnetic radiation prompts people to pursue absorbing materials with better performance. However, absorbing materials with a single loss mechanism usually is unable to obtain better absorbing...

“Matryoshka Doll” Heterostructures Induce Electromagnetic Parameters Fluctuation to Tailor Electromagnetic Wave Absorption

“…[10][11][12] However, single MOFs and their derivatives always suffer from inferior EMW dissipation ability, and inevitably lead to indigent EMW absorption bandwidth. [13] In spite of the achievements made, their EM response abilities and impedance matching are still unsatisfactory due to the limited heterointerfaces, insufficiently exposed defect sites as well as inhibited electron formation/transfer. [14,15] Intuitively, these issues may be simultaneously addressed by modulating compositions and architectures via the integration of two or more different types of MOFs, that is, MOF-on-MOF nanoarchitectonics.…”

Metallic CoNi nanoparticles anchored on heteroatom-doped carbon/MnO nanowires for improved catalytic performance

“…The binding energy peaks located at 854.98 eV (Ni 2p 3/2 ) and 874.28 eV (Co 2p 1/2 ) correspond to Ni 2+ . The XPS data for the product indicate the presence of CoNi alloy nanoparticles, 51 and the detection of Co and Ni ions in the XPS spectra is due to the oxidation of CoNi by oxygen in air.…”

Constructing an efficient electrocatalyst for water oxidation: an Fe-doped CoO/Co catalyst enabled by in situ MOF growth and a solvent-free strategy

“…For comparison, FeSO 4 was directly ball-milled with ZIF-67 and CoO/Co to obtain the corresponding catalysts, which were named Fe-CoO-Z and Fe-CoO/Co-D, respectively. 34…”
