Synthesis of mesoporous carbon using gelatin as source of carbon by hard template technique (endotemplating) and its characterizations had been investigated. The mesoporous silica (SBA-15) as a template was reacted with the gelatie in a H2SO4 solution. The template-polymer composite was then pyrolyzed under a nitrogen flow at 900 °C for 3 h to carbonize the polymer and finished by silica removal from the composite using NaOH solution at temperature of 70 °C The properties of samples were characterized by N2 adsorption- desorption isotherms, transmission electron microscopy (TEM), Fourier Transformation Infra Red Spectroscopy (FTIR), energy dispersive X-ray (EDAX) and Differential Thermal Analysis-Differential Scanning Calorimetry (DTA-DSC). The results showed that the ordered mesoporous carbon was obtained after dehydration, pyrolysis and silica removal process. The presence of nitrogen atoms in the gelatin as the precursors of carbon improved the thermal stability of the carbon. The mesoporous carbon sample have high content of carbon (85 wt.%) and thermal stabliity (up to 1400 °C), specific surface areas of 580 m 2 /g, total pore volumes of 0,5 cm 3 /g, and pore diameter of 3,8 nm.
