Metal-organic frameworks derived porous hollow Co/C microcubes with improved synergistic effect for high-efficiency microwave absorption

High-performance microwave absorption materials with strong absorption and thin thickness have increasingly become a reach hotspot. Here, we successfully prepared a novel porous hollow Co/C microcube by controlling the pyrolysis of the Co-based metal-organic frameworks (MOFs) precursor. The phase composition, microstructure, porosity, and magnetic properties were well modified by controlling the pyrolysis temperature. The multiple components (Co...
