“…[1][2][3][4][5][6][7][8][9][10][11] Due to the environmental concerns and fast depletion of the fossil fuels, there is a robust attraction in the preparation of carbon materials from the natural renewable precursors. The renewable resources like tannin, sucrose, and olive stone have recently gained attention against the current precursors such as synthetic organic polymers, petroleum-and coal tar pitch for the preparation of carbon foams.…”

The carbon foams prepared by the thermo-foaming of dispersions of activated carbon (AC) powder of various average particle sizes (4.9 to 15 lm) in an aqueous sucrose resin were characterized. The stability of the wet foams increased with the decrease in the AC particle size as finer particles preferentially adsorbed on the air-resin interface. The particle agglomeration leading to the foam collapse was observed at lower AC powder to sucrose weight ratios with the finer powders. The cell size (0.33-2.34 mm), foam density (0.1151-0.2281 g/cm 3 ), and compressive strength (0.16-2.77 MPa) of the carbon foams depend on the AC particle size as well as the AC powder to sucrose weight ratio. The thermal conductivity of the carbon foams (0.036-0.049 W m À1 K À1 ) was much lower than that of the vitreous carbon foams of similar densities. The foams were fire resistant and amenable to machining with the conventional machines and tool.

“…Fabrication of the carbonaceous foams was achieved by the replication process [2]. Slight variations to the process presented in [2] were introduced in order to incorporate the TiC nanoparticles. In general terms, the process consists of infiltrating a liquid mesophase pitch (graphite precursor) doped with TiC nanoparticles into preforms of packed particles of NaCl supporting TiC nanoparticles on its surface.…”

TiC-supported metals are systems of great importance in catalysis science and technology. Albeit their interest, catalysts based on monoliths consisting of TiC-containing carbonaceous foams have not yet been fabricated. This work aims to present a route for fabrication of mesophase pitch-derived open-pore graphite foams with TiC nanoparticles selectively distributed in two locations: at the surface of the pore cells, able for metal-support, and in the bulk, essential to achieve high degree of graphitization for

“…Among the manufacturing techniques, the infiltration of martyr preforms, also known as the replication (predesign) method, allows the best control over the material. This method was traditionally used to produce open-pore metal foams and recently adapted to produce carbon/graphite foams [18]. The replication method consists of the infiltration with molten metal or any other liquid precursors of a porous template preform that is later removed by dissolution or controlled reaction to leave a foam material with a porous structure that replicates the original preform.…”

Recently, open-pore foam materials have acquired great interest in several technological sectors due to their excellent properties of low density, great specific surface area, adjustable thermal conductivity, and high-energy absorption. The replication method has proved to be one of the most widely used techniques for their manufacture, allowing a perfect control of the pores' characteristics from which the main properties of the foams derive. However, these properties have limited the use of these materials in ultimate applications of the most demanding emerging technologies. This chapter reviews recent developments of open-pore foams that have been modified by the incorporation of new phases in order to enhance their properties. The inclusion of new phases taking part of the microstructure or modifying the pore surfaces allows these materials to be considered promising for the most modern applications including, among others, thermal dissipation, catalytic supports, and medical implantology.
