CoNiiO sub(2)iO sub(2) and CoNiiriO sub(2) Microspheres with Strong Wideband Microwave Absorption

The synthesis of CoNiiO sub(2)iO sub(2) core-shell and CoNiiriO sub(2) yolk-shell microspheres is reported for the first time. Owing to the magnetic-dielectric synergistic effect, the obtained CoNiiO sub(2)iO sub(2) microspheres exhibit outstanding microwave absorption performance with a maximum ref...

More Information
Summary:The synthesis of CoNiiO sub(2)iO sub(2) core-shell and CoNiiriO sub(2) yolk-shell microspheres is reported for the first time. Owing to the magnetic-dielectric synergistic effect, the obtained CoNiiO sub(2)iO sub(2) microspheres exhibit outstanding microwave absorption performance with a maximum reflection loss of -58.2 dB and wide bandwidth of 8.1 GHz (8.0-16.1 GHz, < -10 dB).
