Fabrication of yolk-shell NiCo alloy@C composites derived from trimetallic metal–organic frameworks as light-weight and high-performance electromagnetic wave absorbers

Developing the high-performance electromagnetic wave (EMW) absorbers with the characteristics of thin thickness, broad bandwidth and strong absorption against the increasingly serious electromagnetic pollution was still a great challenge. In this work, NiCo [email protected] (NCC) composites were fabricated through high-temperature pyrolysis of trimetallic NiCoZn metal-organic framework. Results showed that the NCC composites displayed a unique...
