Nanoporous Carbon from Water Hyacinth Via Hydrothermal Carbonization

Nanoporous carbon materials have been successfully synthesized from water hyacinth via hydrothermal carbonization (HTC). This research was studied the effect of hydrothermal temperature from 160 - 200 °C and reaction time for 4 - 24 h. Afterwards, carbonization was carried out at the temperature of 600 - 900 °C for 2 h in N₂ atmosphere for developing porosity and even removing contaminants of hydrothermal char to obtain the porous carbon. The physico-chemical properties of nanoporous carbon materials were comprehensively characterized through Scanning electron microscope (SEM), Fourier transforms infrared spectroscopy (FT-IR), CHN elemental analysis, X-ray diffraction (XRD) and BET analysis. The adsorption capacity and carbon content of nanoporous carbon materials from water hyacinth were increased with increased hydrothermal carbonization temperature and time. Performing HTC at 200 °C for 12 h. Is the optimum condition to synthesis of precursor materials for good adsorbent.
