Abstract

In general, carbon is abundantly available in the form of biomaterials derived from plants, either as bio-products or bio-waste. In this study, we investigated carbon characteristics of corncob powders, which were synthesized using a coprecipitation method and heated at 400 °C. The samples were analyzed using thermogravimetric analysis (TGA), X-ray diffraction (XRD), energy dispersive X-ray (EDX), scanning electron microscopy (SEM), and Fourier-transform infrared (FTIR). The results of this study indicated that samples heated at 100 °C encompass a crystalline phase, while samples heated at 400 °C formed an amorphous phase. Morphology of all samples was formed in a micrometer size in the form of lumps with the highest carbon content of 72.3%. The C=C functional group in the carbonated samples at 400 °C was detected at a wavenumber of 1593 cm-1, which is a characteristic of carbon in graphite and graphene.
