| 摘 要： | 以二甲苯为炭源、二茂铁为催化剂,采用CVD法在竹炭上催化气相生长了一维纳米炭,采用扫描电镜、透射电镜及氮吸附仪等对一维纳米炭/竹炭的形貌、微结构及比表面积进行了表征,并研究了一维纳米炭/竹炭复合材料对重金属离子Pb2+的吸附性能.结果表明,采用CVD法可以在竹炭上生长一维纳米炭,且随着气相生长时间的延长,竹炭上的一维纳米炭变得更加浓密而均匀.竹炭上生长一维纳米炭后,对Pb2+的吸附能力增强,硝酸氧化处理可以进一步提高一维纳米炭/竹炭对Pb2+的吸附能力.

| Abstract: | Carbon nanotubes were grown on bamboo charcoal by CVD method, with xylene as carbon source and ferrocene as catalyst precursor.The morphology, structure and specific surface area were characterized by SEM, TEM and nitrogen adsorption analyzer.We investigated the adsorption of lead ions in aqueous solution by CNTs/BC.The results showed that CNTs were successfully grown on bamboo charcoal by CVD method, and CNTs became denser and more uniform with the hold time.We also found that CNTs/BC composites exhibited ... |
