【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。更多还原

【Abstract】 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,H 2 yield was 75%,the produced carbon nanotubes was multi-walled carbon nanotubes(MWCNTs)(being of relatively higher and low defect).更多还原
