철 및 탄소 나노튜브를 포함하는 개선된 촉매. 본 발명은 탄소 나노튜브 및 철-기재 입자를 포함하는 촉매를 제조하는 방법에 관한 것으로, 방법은: a) 철-함유 물질의 존재 하에 탄소-함유 물질의 증기의 화학 기상 증착을 통해 철-기재 입자를 포함하는 탄소 나노튜브를 제조하고; b) 철-기재 입자를 포함하는 탄소 나노튜브를 산화 조건에 두어 철-기재 입자를 덮는 그래파이트 층을 선택적으로 에칭하여, 그렇게 함으로써 철-기재 입자를 탄소 나노튜브의 표면에 노출시키고 철-기재 입자를 적어도 부분적으로 산화시키고; c) 철-기재 입자를 적어도 부분적으로 환원시키기 위해 철-기재 입자를 포함하는 탄소 나노튜브를 환원 조건에 두는 단계를 포함한다. 촉매는 일산화탄소 또는 이산화탄소로부터 탄화수소의 제조에, 또는 탄소 포집 및 이용에 사용될 수 있다. Improved catalyst comprising iron and carbon nanotubes. The invention relates to a process for making a catalyst comprising carbon nanotubes and iron-based particles, the process comprising the steps of: a)preparing carbon nanotubes comprising iron-based particles by chemical vapour deposition of a vapour of a carbon-containing substance in the presence of an iron-containing substance; b) subjecting the carbon nanotubes comprising iron-based particles to oxidising conditions to selectively etch away graphite layers covering the iron-based particles, thereby exposing the iron-based particles at the surface of the carbon nanotubes and at least partially oxidising the iron-based particles; and c) subjecting the carbon nanotubes comprising iron-based particles to reducing conditions in order to at least partially reduce the iron-based particles. The catalyst may be used in the manufacture of hydrocarbons from carbon monoxide or carbon dioxide, or for carbon capture and utilization.
