GREEN SYNTHESIS OF HIGHLY POROUS CARBON NANOSPHERES FROM ARECANUT

摘要

The present invention provides a method for synthesizing of carbon nanospheres, wherein the method comprising the step of utilizing arecanut as a precursor and template, preparing arecanut in powder form of size 60-70 micrometer using sieving method, utilizing pyrolysis process for a for thermochemical decomposition of arecanut powder, carbonizing the arecanut in a tube furnace in nitrogen atmosphere, controlling the temperature and pressure of the tube furnace at predetermined level to effectively remove ash formation during the pyrolysis process, cooling the pyrolyzed arecanut powder at a rate between 1 and 10oC/min, and obtaining carbon nanospheres with small particles sizes in the range of 30nm to 90 nm.
