In this work, we developed a one-step process for synthesizing carbon nanofibers encapsulated Ni magnetic nanoparticles. The process for CO2 converted to solid carbon can be applied in many fileds:
1.The carbon-encapsulated magnetic Ni nanoparticles can apply to remove the organic compounds and heavy metal ion and can be rapidly separated from water.
2.The magnetic material can be used as a biomaterial widely applying to protein separation.
3.The carbon-encapsulated magnetic Ni nanoparticles can be combusted to generate heat energy, while the Ni metal is reused for the reaction of CO2 converted to solid carbon.
