Abstract

In this study, we impregnated nanometal samples having various concentrations 0, 1000, 3000, and 5000. ppm in biomass in order to make carbonized biomass. We analyzed the properties of the impregnated samples through thermogravimetry/differential thermal analysis (TG-DTA), iodine adsorptivity, fixed carbon ratio, pore distribution, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The best results were observed for a nanometal concentration of 5000. ppm. After the first heat treatment, carbonization, and activation processes, the fixed carbon ratio and iodine adsorptivity were increased by 11.07% and 42. mg/g, 11.07% and 198. mg/g, and 46.7% and 1185. mg/g, respectively. Through repeated experiments, we established the most effective process for impregnating a nanometal in biomass.
