两步法制备蔗渣基碳纳米管
Two-step preparation of bagasse-based carbon nanotubes
摘要
Abstract
Bagasse-based carbon nanotubes(CNTs)were prepared using a two-step method.First,biomass pyrolysis gas was obtained through microwave pyrolysis of bagasse.This gas was then used as a carbon source in a tube furnace loaded with Fe-based catalysts to synthesize CNTs.The CNTs'microstructure was characterized by XRD,SEM,and Raman spectroscopy.The results indicate that using biomass pyrolysis gas for CNT preparation via chemical vapor deposition is effective.The produced CNTs have smooth and intact tube walls,with Raman spectra showing D peak to G peak intensity ratios below 0.5 and 2D peak to G peak intensity ratios above 0.8.This indicates a high degree of graphitization and high purity,offering a new approach for valorizing bagasse waste.关键词
