以生物质为催化剂化学气相沉积制备碳纳米管OA北大核心CSCDCSTPCD
Carbon nanotubes produced by chemical vapor deposition using natural biomass-based catalysts
以富含过渡金属元素铁的天然生物质黑木耳、紫菜、香菇、黑芝麻的炭化粉末作为催化剂前驱体,天然气为碳源,采用化学气相沉积工艺制备了碳纳米管(CNTs).所制CNTs阵列的管径较窄,排列整齐,归因于蘑菇、紫菜和黑芝蔗的碳含量高及铁基纳米颗粒分散均匀.采用黑木耳为催化剂所制CNTs的直径也较窄,但杂乱生长,可能是由于黑木耳的碳含量低及铁基纳米颗粒分布不均匀所致.
Carbon nanotubes (CNTs) were prepared by chemical vapor deposition, using carbonized iron-rich biomass, mushrooms, seaweed, black fungus and black sesame seeds as catalysts, and methane as the carbon source. It was found that CNT arrays with narrow diameter distributions were formed on the catalysts derived from mushrooms, seaweed and black sesame seeds because they have a high carbon yield and as a result iron-based nanoparticles are well dispersed in these…查看全部>>
