High-performance microwave absorption of MOF‐derived Co3O4@N-doped carbon anchored on carbon foam

The excellent electromagnetic wave absorbing properties of carbon fiber composites: the effect of metal content

“…As we all know, the real parts (ε′ and μ′) show the storage capacity of electricity and magnetism, and the imaginary parts (ε″ and μ″) indicate the dissipation capacity. 34 They can be expressed by the following formulas. 35…”

“…As we all know, the real parts ( ε ′ and μ ′) show the storage capacity of electricity and magnetism, and the imaginary parts ( ε ′′ and μ ′′) indicate the dissipation capacity. 34 They can be expressed by the following formulas. 35 ε = ε ′ − jε ′′ = ε 0 ( ε ′ r − jε ′′ r ) = ε 0 ε r μ = μ ′ − jμ ′′ = μ 0 ( μ ′ r − jμ ′′ r ) = μ 0 μ r …”

Ceria-based oxide catalysts supported on metal–organic frameworks: selective oxidation of toluene to CO2 and the doped metal-activity relationship

“…, substitutions, vacancies, and interstitials) can lead to shifts in XRD peak positions. 29 Thus, cerium and metallic oxide may have reduced crystallinity once they are introduced. The wide-angle XRD patterns and diffraction crystal planes of samples at 2 θ angles were obtained by following Joint Committee on Powder Diffraction Standards card numbers.…”

State of the Art and Prospects in Metal-Organic Framework-Derived Microwave Absorption Materials

“…Liu’ group loaded ZIF-67 on the surface of lightweight carbon foam (CF) to act as the precursors of Co 3 O 4 /CF (Fig. 14 h) [ 142 ]. During the high-temperature pyrolysis process, the Co 2+ transferred into Co 3 O 4 sheet embedded on the carbon matrix, which benefited the dual electromagnetic energy attenuation mechanisms (Fig.…”
