Abstract

Abstract: Continuously increasing practical relevance required the mass production of carbon nanotubes (CNTs) through environmentally benign and sustainable routes. In the work, it is found that loading trace amounts of NH4 Cl on rice husk carbon can effectively act as promoters and assisted carbon source inthe catalytic growth of CNTs from polypropylene byNi−Mo−Mg catalysts. The synthesized CNTs was characterized by Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X‐ray diffractometer (XRD), Raman spectroscopy, and Thermogravimetric analysis (TGA). Results show that the added rice husk carbon can take part in the formation of CNTs to a certain extent, and the trace of NH4 Cl incorporated into rice husk carbon can significantly improve the conversion rate of polypropylene. The CNT products possess multiwalled structures and highgraphitization degrees. Finally, the prepared CNTs were investigated for the removal of methylene blue (MB) from water. Abstract : Carbon nanoubes were synthesized from polypropylene and NH4 Cl/Rice husk carbon with the presence of Ni−Mo−Mg catalysts. The NH4 Cl/Rice husk carbon was prepared by the loading of trace NH4 Cl on rice husk carbon, which was demonstrated to function effectively as promoters and assisted carbon sources in above carbonization. The carbon nanotubes prepared by this method showed excellent adsorption performance for the removal of methlene blue.
