FeMnC complex derived from hollow FeMn PBA precursor for highly efficient microwave absorption†
Abstract
In this study, we employed a coprecipitation method to synthesize hollow FeMn PBA precursors. After pyrolysis under inert conditions, a core–shell FeMnC complex with a carbon layer wrapped metal core was obtained. An effective absorption width of 6.4 GHz and a minimum reflection loss of 60.3 dB at 2.3 mm exhibit enhanced microwave absorption performance.
