Carbonized nano-Co3O4 particles and diatomite were used for preparation of the composite of carbonized nano-Co3O4/diatomite by pyrolysis method, the magnetic and absorption properties were studied. The composite was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, vibrating sample magnetometer. The results show that the superparamagnetic nano-Co3O4 particles with average size of 50nm and amorphous activated carbon are uniformly dispersed in the surface and pores of diatomite to form a stable composite. Carbonized nano-Co3O4/diatomite composite indicates high magnetic and microwave absorption performance with maximum reflection loss of -14.7dB, <-10dB frequency range about 14-18GHz and bandwidth of 4GHz.
