The purpose of this study is to develop new porous carbon materials by carbonizing wood-based materials. Wood-based materials are composite materials made from wood and non-wood materials manufactured in processes involving pressure and heat treatment. Wood-based materials have been on the market for decades and there is a wide range of products (plywood, particleboards, medium density fibre boards (MDF) and oriented strand boards (OSB)). One of the advantages of wood-based materials used as precursors for porous carbon materials is the simple and cost-effective production technique. Moreover, it is possible to make adjustments for a wide range of macro-structures and micro-structures by selecting different densities and particle sizes. Compared with solid wood wood-based materials show much greater homogeneity, isotropy and reproducible characteristics. Another great advantage is the fact that carbon materials can thus be produced from a renewable resource. A broad variety of commercial available and specific developed wood-based materials are carbonized to produce the porous carbon materials which are characterized by means of determination of density, porosity, yield, dimensional changes, TGA/DTA, SEM, mechanical testing and surface area. Additionally the influence of the carbonization temperature on this characteristics is investigated. Those porous carbon materials can be used for a number of applications, including filters, adsorbents, electrodes and catalyst supports. More recently they have been found as precursors for reaction-formed structural ceramics and for composite materials.
