The present disclosure relates to the technical field of microbial electrochemical technology, in particular to a graphene-magnetite conductive skeleton electrode, a preparation method and application thereof, and a method for treating petrochemical wastewater. In the present disclosure, the surface roughness of the graphite rod electrode can be increased by the conductive skeleton modified on the surface of the graphite rod electrode, which is beneficial to the enrichment of microorganisms. The increase in the load of microorganisms will mean the amount of electroactive microorganisms will also increase, which will further improve the electron transfer ability, and because the material of the modified layer is a conductive material, it is also more conducive to the transfer of electrons; at the same time, the conductive skeleton modified on the surface of graphite rod electrode can also further enhance the transmission distance of electrons because of the skeleton constructed.

A titanium sulfide (TiS) nanomaterial and a composite material thereof for wave absorption are disclosed. The TiS nanomaterial is in a form of dispersed micro-particles which are bulks formed by stacking two-dimensional nano-sheets. The TiS nanomaterial is a bulk formed by stacking two-dimensional nano-sheets, thereby having a laminated structure that improves the wave absorption effect. In addition, experimental results demonstrate that the TiS nanomaterial with a dose of 40 wt% has the most excellent wave absorption performance, with a minimum reflection loss up to -47.4 dB, an effective absorption bandwidth of 5.9 GHz and an absorption peak frequency of 6.8 GHz, which are superior to those of existing two-dimensional bulk materials. One of reasons for the excellent wave absorption performance of the TiS nanomaterial may be because the laminated micro-morphology of TiS results in the electromagnetic wave refraction loss.
