Technical Description The chemical conversion of CO2 via catalytic reactions is considered the most promising process for CO2 utilization. We have described a novel method for converting CO2 to carbon nanofibers through catalytic hydrogenation of CO2 over Ni catalysts. Few reports have mentioned the direct formation of carbon nanofibers from CO2. This process could be an important CO2 recycling technique because solid carbon can be conveniently stored. The magnetic carbon materials have been applied in the fields:
1.The material can apply to remove the organic compounds and heavy metal ion and can be rapidly separated from water.
2.The material can be used as a biomaterial widely applying to protein separation.
3.The material can be combusted to generate heat energy, while the Ni metal is reused for the reaction of CO2 converted to solid carbon.
4.The material can be used for the removal of formaldehyde in air and anti-bacteria and -virus.
Scientific Breakthrough There have been no reports of the one-step synthesis of oxidized carbon nanomaterials with magnetic metal and straightforward synthesis of hydrophilic carbon nanomaterials with magnetic metal is challenging. In this work, hydrophilic, strongly magnetic Ni with strong magnetization were directly synthesized by CO2 hydrogenation. The magnetic carbon materials have been applied in the fields:
1. To remove the organic compounds and heavy metal ion from water.
2. Applying to protein separation.
3. It can be combusted to generate heat energy, while the Ni metal is reused for the reaction of CO2 converted to solid carbon.
4. To remove formaldehyde in air
5. Used as the anti-bacteria and –virus materials.
Industrial Applicability Recently, we have described a novel method for converting CO2 to carbon nanofibers through catalytic hydrogenation of CO2 over Ni catalysts. If CO2 can be used as a carbon source for the conversion of CO2 into solid carbon, this process could be an important CO2 recycling technique because solid carbon can be conveniently stored. The magnetic carbon materials have been applied in the fields:
1.To remove the organic compounds and heavy metal ion and can be rapidly separated from water.
2.To be used as a biomaterial widely applying to protein separation.
3.It can be combusted to generate heat energy, while the Ni metal is reused for the reaction of CO2 converted to solid carbon.
4.It can be used for the removal of formaldehyde in air and anti-bacteria and -virus.
