Carbon base foam is one of the different types of carbon material an‎d can have coolers. Features of this foam include high special surface, hydro‎phobic surface, high thermal stability, an‎d high electrical an‎d thermal conductivity. Also, the use of carbon foam can be the lithium battery, carbon absorption, thermal management an‎d sensors. One of the methods of making carbon foam foam is the biodegradable preparing. In this study, the carbon foam method from the biodegradable was studied. The purpose of this project is to examine the process factors on the synthesis, the cohesion an‎d the properties of carbon foam from the biodiversity. For this purpose, the carbon powder was first prepared by walnut peerlys at 600 ° C an‎d then carbon 600 ° C along with a blue phase including deionized water an‎d sucrose under the drying operation. The foam was subsequently placed to pyrulosis in the neutral atmosphere at 900 ° C. Also, in order to increase the special surface, the test was performed on the active carbon of walnut skin. In this context, the special surface of the foam from walnut powder was obtained by 1000 m2g. The phase determination an‎d the crystallization of the samples were done with the help of X -ray an‎d Raman beam pattern analysis. The morphology of the samples was also eva‎luated by the assistance of the scanning electron microscopy as well as the special surface of the foams with the help of adsorption an‎d adsorption of nitrogen gas BET.
