    Hydrochar have been successfully synthesized from Cattail leaves via hydrothermal carbonization. This research study the effect of hydrothermal temperature (160-200°C) and reaction time (4-24 h) to develop porosity and surface area. The sample have been characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy were employed to characterize morphology, surface function and disorder in carbon structure respectively. The results revealed that hydrothermal-carbonization process affect on the properties of hydrochar. The hydrothermal temperatures and time were increased resulted in the decomposition of hydrochar gradually increased amorphous carbon and aromatic groups on surface of hydrochar. Cattail leaves was hydrothermal carbonization at 200°C for 12 h resulted in the most degradation of hemicellulose and cellulose.

    Nanoporous carbon materials were successfully synthesized via hydrothermal carbonization with acid additives. In this study the effect of hydrothermal temperature (160-200 °C), hydrothermal time (4-24 h) and influence of acid additive (HCl, HNO<inf>3</inf>, H<inf>2</inf>SO<inf>4</inf> and H<inf>3</inf>PO<inf>4</inf>) have been chosen in order to improve the surface structure. The samples have been characterized by scanning electron microscopy, nitrogen sorption, Fourier transform infrared spectroscopy and X-ray diffraction. The experimental results revealed that hydrothermal carbonization process and acid addition have effect on the properties of catalyst support. The results indicated that hydrothermal process at 200°C for 12 h and activation with H<inf>3</inf>PO<inf>4</inf> at 900 °C for 2 h, exhibited the highest surface area, porosity and pore volume leading to increased distribution of metal on the carbon support.
