The results show that the higher yield of CNF obtained by decomposition of carbon monoxide than that of methane over a series of alumina supported Ni/Fe catalysts prepared by deposition-precipitation method is attributed to the role of produced carbon dioxide and the different carbon diffusion mode on metal particle.

结果发现： 1。当采用CO为碳源时，催化剂在36小时内具有较为稳定的活性，当采用CH〓为碳源时，催化剂中Fe的存在不利于得到较高产率的纳米碳纤维；不同的纳米碳纤维产率与生长过程中形成的CO〓及碳在金属表面或者体相中的传递行为密切相关； 2。

Because steam activation carbon has a narrower and more extensive microporosity than carbon dioxide activation carbon, stream is the only oxidising agent in this paper.
