To our knowledge, the utilization
of chitosan-derived materials
in microwave absorbing is currently scarce. Herein, for the first
time, by fully exploiting its potential properties via facile means,
chitosan was employed as the exclusive joint source of carbon and
nitrogen, and the inherent N-doped honeycomb-like carbon/Fe<sub>3</sub>O<sub>4</sub> composites with favorable versatility that can
efficiently treat microwave interference and even wastewater pollution
were controllably prepared. The optimal microwave absorbency is attractive,
of which the minimum reflecting loss reaches to −59.5 dB, and
the maximum effective absorbing bandwidth is 5.36 GHz when filler
content is only 10%. Beyond the major trying, another function for
wastewater treatment was also demonstrated by excellent toxic Cr(VI)
adsorption and peroxymonosulfate activation for organic pollutants
(azo-dye Orange II) degradation. More significantly, the embedding
magnetic component makes it convenient to be magnetically separated
from the testing solution. Totally, these N-doped honeycomb-like carbon/Fe<sub>3</sub>O<sub>4</sub> composites with versatility prepared by simple
methods not only open a new road for the diversified utilization of
chitosan but also would possibly make a referrable guidance to the
design or even synthesis for superior microwave absorption and environmental
remediating materials.
