摘要
With the increasingly serious problem of environmental pollution, the concept of environmental protection has become more and more popular, and green synthesis has attracted many attentions. In view of the situation, we report a novel MoS2@nitrogen doped carbon hybrid decorated with ultrasmall cobalt ferrite nanoparticles(MoS2@[email protected]2O4 hybrid), which was skillfully prepared via one pot green reaction. The whole synthesis process of the hybrid is environmental friendly, and no heavy metal ions remain in the final reaction system. The microstructure, crystal form, chemical elemental composition, surface functional groups, thermal stability and EM wave absorbing performance of the obtained products were systematically investigated. When the calcination temperature is 600 °C, the hybrid performs optimum capability for EM wave. The reflection loss curve suggested that the MoS2@[email protected]2O4-600 hybrid exhibits excellent EM wave absorption performance, with a minimum reflection loss value of −46.7 dB at the specimen thickness of 2.4 mm, which can be attributed to the fair electromagnetic matching, interface polarization, interface relaxation and some other factors.
