In this paper, a carbon foam of gelatin (CFG) with large pore size was synthesized for the first time using gelatin as a carbon precursor and sulfuric acid as the catalyst which is pyrolyzed at 900 C for 3 h under argon atmosphere flow. The structural and textural properties of the CFG samples were characterized by scanning electron microscopy (SEM), energy dispersive X-Ray (EDX), thermal gravimetry analysis (TGA), Fourier transforms infrared (FTIR) spectroscopy and nitrogen adsorption–desorption techniques. The surface area of CFG sample is about 62.5 m²/g and pore size with average size range at 20-30 nm  and broken hole size up to 10 12µ"> m according to the N₂ isotherm curve and SEM. The high pore size of CFG and dominated by carbon and oxygen with the unique structure composed of disordered arrays of carbon nanopipes in a macropore system. TGA curve showed degradation of gelatin due to water weight loss and decomposition reaction of gelatin. The TGA results indicated that there was big CFG degradation at 1000 ºC  that showed the high thermal stability of CFG. The study on thermal behavior and character of CFG structural would create a new generation of the hard template.
