Magnetic metal nanostructures have exhibited good electromagnetic wave (EMW) absorption properties. However, the surface of is easily oxidized upon exposure to air, leading bad stability EMW We use metal-organic framework structure as a template fabricate hollow N-doped carbon polyhedron containing CoNi alloy nanoparticles embedded within graphene (CoNi@NG-NCPs). The atomic ratio Co/Ni can be tuned from 1:0.54 1:0.91 in CoNi@NG-NCPs. Experimental results demonstrate that properties...
