Abstract: Nanoporous support materials were successfully synthesized from biomass via hydrothermal carbonization with base additives. This research study the effect of hydrothermal temperature (160-200 °C), hydrothermal time (4-24 h) and influence of base additive (NaOH, KOH, Na₂CO₃ and K₂CO₃) 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 KOH 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.
