Graphene is highly desirable as an electromagnetic wave absorber because of its high dielectric loss and low density. Nevertheless, pure graphene found to be non-magnetic contributes microwave energy absorption mostly loss, the parameters graphene, which are out balance, result in a bad impedance matching characteristic. In this paper, we report facile solvothermal route synthesize laminated magnetic graphene. The results show that there have been significant changes properties when compared...

Even though Fe-N/C electrocatalysts with abundant Fe-Nx active sites have been developed as one of the most promising alternatives to precious metal materials for oxygen reduction reaction (ORR), further improvement their performance requires precise control over at molecular level and deep understanding catalytic mechanism associated each particular structure. Herein, we report a host–guest chemistry strategy construct Fe-mIm nanocluster (NC) (guest)@zeolite imidazole framework-8 (ZIF-8)...

Metal organic framework (MOF)‐derived nitrogen‐enriched nanocarbons have been proposed as promising metal‐free electrocatalysts for oxygen reduction reaction. However, the characteristic microporous feature of MOF‐derived carbon determined by MOF structure significantly hinders mass transfer and exposure active sites, resulting in unsatisfactory electrocatalytic performance. Here an situ confinement pyrolysis strategy that can simply but efficiently transform monodisperse ZIF‐8 polyhedrons...

Although graphene nanomesh is an attractive 2D carbon material, general synthetic routes to produce functional in large-scale are complex and tedious. Herein, we elaborately design a simple two-step dimensional reduction strategy for exploring nitrogen-doped by thermal exfoliation of crystal- shape-modified metal-organic frameworks (MOFs). MOF nanoleaves with rather than 3D crystal structure used as the precursor, which further thermally unraveled into using metal chlorides exfoliators...

A transition-metal-nitrogen/carbon (TM-N/C, TM = Fe, Co, Ni, etc.) system is a popular, nonprecious-metal oxygen reduction reaction (ORR) electrocatalyst for fuel cell and metal-air battery applications. However, there remains lack of comprehensive understanding about the ORR electrocatalytic mechanism on these catalysts, especially roles different forms metal species performance. Here, novel CuN/C with hybrid Cu coordination site successfully fabricated simple but efficient...

This study demonstrates a special ultrathin N-doped graphene nanomesh (NGM) as robust scaffold for highly exposed Fe-N4 active sites. Significantly, the pore sizes of NGM can be elaborately regulated by adjusting thermal exfoliation conditions to simultaneously disperse and anchor moieties, ultimately leading loaded Fe single-atom catalysts (SA-Fe-NGM) morphology. The SA-Fe-NGM is found deliver superior oxygen reduction reaction (ORR) activity in acidic media (half-wave potential = 0.83 V vs...

The electrochemical CO2 reduction reaction (CO2RR) using renewable electricity is one of the most promising strategies for reaching goal carbon neutrality. Multicarbonous (C2+) products have broad applications, and ethanol a valuable chemical fuel. Many Cu-based catalysts been reported to be efficient electrocatalytic CO2RR C2+ products, but they generally offer limited selectivity current density toward ethanol. Herein, we proposed silica-mediated hydrogen-bonded organic framework...

Low-density ordered mesoporous carbon−silica nanocomposites with different Fe contents have been prepared by a facile solvent-evaporation-induced self-assembly approach. Magnetic metal nanocrystallines are highly dispersed in the composites due to situ carbothermal reduction. The optimal reflection loss calculated from measured permittivity and permeability is −34.4 dB at 13.1 GHz. Moreover, electromagnetic wave absorption less than −10 found exceed 5.0 GHz for an absorber thickness of 2 mm....
