摘要
以乙醇为碳源,采用浸渍法制备的担载量为Fe（5％）/C催化剂,利用化学气相沉积法协同制备碳纳米管和氢气,分析了裂解温度（500～800℃）对于产生氢气产率和碳纳米管品质的影响.对于Fe（5％）/C催化裂解乙醇,最佳的反应温度为600 ℃,碳管的品质较好,氢气的产率最高为75％,生成的碳管为多壁碳纳米管.
Ethanol as carbon source,the effects of reaction temperature on the yield of hydrogen and the quality of carbon nanotubes （CNTs） over the Fe（5％）/C from the decomposition were investigated systematically.Ethanol decomposition was studied over Fe （5％）/C to produce hydrogen and carbon nanotubes by chemical vapor deposition at the temperature of 500 ～ 800 ℃.The optimal reaction temperature was 600 ℃ for hydrogen and the growth of MWCNT from ethanol decomposition over the Fe（5％）/C,H2 yield was 75 ％,the produced carbon nanotubes was multi-walled carbon nanotubes （MWCNTs） （being of relatively higher and low defect）.
