 N-I-Co-LDHS at ZN-O nanorods were synthesized and subsequently heat treated to create NICO at C-CNO composites. The resulting material exhibited excellent absorption properties, with a reflection loss of minus 60.97 dB at a thickness of 2.3 mm and a wideband absorption of 6.08 GHz at a thickness of 2.0 mm. This study demonstrates the potential of LDHs as a promising material for microwave absorption applications. This article was authored by Jin Wei Wang, Zhe Wei Jia, Xiu Hualu, and others.
