Abstract

Abstract: 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, HNO3, H2 SO4 and H3 PO4 ) 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 H3 PO4 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
