Abstract :In recent years, ordered porous carbon materials (OPCM) have critical application in many important fields because of their porous structure and huge spesific surface area. Some spesific properties of ordered porous carbon materials like low density, chemical stability, strong mechanical strength, and very good electrical conductivity provide using them in spesific and advenced technologic field. They get extensive usage area especially, as an electrod in electrochemistry, hydrogen storage, heterogen catalys, gas adsorbtion and as an adsorbent in seperation processing. Ordered porous materials are classified base on pore radius (a) microporous (pore size 2 nm 50 nm). Traditional porous carbon materials like activated carbon and carbon molecular sieves are activated, via firstly carbonisation of charcoal, wood, fruit shell, fruit seed and natural polymers and then physical and chemical activation of them. In this study, fine granulated hazelnut shell was mixed together with SBA-15 consist of family of mesoporous silica nanoparticul (MSN) as a template, and then half of it carbonised again together in furnace at 900oC in nitrogen atmosphere (FC). Other half of it used without carbonisation(F). Obtained ordered porous carbon materials (FC and F) from hazelnut shell coal were characterised by thermal gravimetry (TG/DTA), N2 adsorbtion-desorbtion isoterm, X-ray powder diffraction, SEM/TEM and Elemental Analysis.
