甲烷催化裂解制氢和碳纳米管钴共生材料

Hydrogen production from catalytic cracking of methane and cobalt symbiosis materials of carbon nanotubes

采用配合物前驱体法、浸渍法、直接混合法3种方法制备负载型金属催化剂,研究其对甲烷催化裂解产氢和碳纳米管材料的催化性能。结果表明,采用配合物前驱体法制备的催化剂有着明显的制氢效率以及具有较高的碳纳米管材料产量。控制不同的反应温度、反应时间等能够做到调控碳纳米管材料的管径和长度。

The supported metal catalyst was prepared by three methods:complex precursor method,impregnation method and direct mixing method.The catalytic performance of the supported metal catalyst for hydrogen production from methane catalytic cracking and carbon nanotube material was studied systematically.The results show that the catalyst prepared by complex precursor method has obvious hydrogen production efficiency and high yield of carbon nanotube material.The diameter and length of carbon nanotube materials can be controlled by controlling different reaction temperatures and reaction time.
