Growing CoNi nanoalloy@N-doped carbon nanotubes on MXene sheets for excellent microwave absorption
文献摘要：
Recently,two-dimensional MXene materials have attracted numerous attention in electromagnetic wave shielding/absorption.Hybridizing magnetic materials and constructing multi-dimensional structures in MXene is highly beneficial to improve electromagnetic wave absorption properties.Herein,we demon-strate a strategy for in situ growing OD CoNi nanoalloy-encapsulated 1D N-doped carbon nanotubes on a 2D Ti3C2Tx MXene sheet through an electrostatic assembly process followed by a high-temperature pyrol-ysis process.The resultant 201-structured MXene-CoNi@N-doped carbon nanotube(MXene-CoNi@NCNT)composites displayed high surface areas(55.6-103.7 m2/g),moderate magnetism(19.8-24.6 emu/g),and excellent thermal oxidation stabilities(＞307℃).In addition,the unique 2D/OD/1D architectures en-trusted the composites with abundant interfaces,various defects,and numerous nitrogen dopants.Taking advantage of the special 201 structure and the existence of both magnetic and dielectric loss,the MXene-CoNi@NCNT composite showed great impedance matching and strong attenuation performance.A strong reflection loss of-55.3 dB was achieved when the coating thickness was 2.1 mm,and a wide effective absorption bandwidth of 4.3 GHz was achieved at a thickness of 1.5 mm,much superior to that of similar absorbers.This work demonstrates a novel strategy for designing electromagnetic wave absorbers with magnetic and dielectric losses accompanied by multiple dimensional structures.
