ZnO/nitrogen-doped carbon nanocomplex with controlled morphology for highly efficient electromagnetic wave absorption
文献摘要：
In this work,zeolitic imidazolate framework-8(ZIF-8)with yolk-shell and hollow structures were pre-pared by a convenient chemical etching method.A subsequent pyrolysis of ZIF-8 enabled one to pro-duce ZnO/nitrogen-doped carbon nanocomplexes with original ZIF-8 morphology,where hollow struc-ture showed superior electromagnetic wave absorption capacity and was responsible for matching the impedance of free space.The minimum reflection coefficients of hollow ZnO/nitrogen-doped carbon nanocomplexes were-51.2 dB(700℃)and-52.4 dB(800℃),respectively,whereas the effective ab-sorption band width was as large as 4 GHz and the content of pyrolyzed hollow ZIF-8 was 15 wt％,which was inferior to the level among similar electromagnetic wave(EMW)absorption materials.The conve-nient and facile strategy paves the way toward designing hierarchical structures for highly efficient and light-weight electromagnetic wave absorbers.
