Fe/CeO₂ catalysts with different ferrum loading were prepared by solid state melting method. Ethanol decomposition on those catalysts at different temperature (600, 700, and 800°C) has been studied. To evaluate the catalytic performance in ethanol decomposition, gaseous and solid products produced from ethanol decomposition were collected and analyzed; H₂ and multi-walled carbon nanotubes (MWCNTs) were obtained. In these experiments, ethanol decomposition on Fe (30 wt%)/CeO₂ at 600°C showed the maximum H₂ yield (the maximum H₂ yield was 94%, which was higher than that of previous reports). In addition, other gaseous products include CH₄ and CO were observed, but CO₂ was not be detected. The content of H₂, CO, and CH₄ were 60 ~ 80%, 20 ~ 25%, and 0 ~ 10%, respectively. MWCNTs have formed in ethanol decomposition process, the quality and purity of MWCNTs increase with increasing temperature, and the material with the carbon-encapsulated metal structure was obtained.

采用固态熔融法制备了不同铁负载量的Fe / CeO ₂催化剂。研究了在不同温度（600、700和800°C）下这些催化剂上的乙醇分解。为了评估乙醇分解的催化性能，收集并分析了乙醇分解产生的气态和固态产物。获得了H ₂和多壁碳纳米管（MWCNT）。在这些实验中，乙醇在600°C的Fe（30 wt％）/ CeO ₂上分解显示出最大的H ₂产率（最大H ₂产率为94％，高于以前的报道）。另外，观察到其他气态产物包括CH ₄和CO，但是CO ₂未检测到。H ₂，CO和CH ₄的含量分别为60〜80％，20〜25％和0〜10％。在乙醇分解过程中形成了多壁碳纳米管，随着温度的升高，多壁碳纳米管的质量和纯度逐渐提高，得到了具有碳包封金属结构的材料。
