Highly porous graphitic materials prepared by catalytic graphitization

Preparation and supercapacitive performance of clew-like porous nanocarbons derived from sucrose by catalytic graphitization

“…The formation of graphitic structures around the catalysts takes place through the dissolution of amorphous carbon into the Ni particles followed by the precipitation of graphitic carbon [17]. According to the literature, several microstructures of graphitic carbons, such as ultrathin graphitic nanostructures on solid carbon [18], rod-like structure [19], Sponge-like structure [20] and random nanocoils nanostructure [21] have been prepared by different methods.…”

Review on the recent progress of carbon counter electrodes for dye-sensitized solar cells

“…There are three well-known methods that have been used for the preparation of graphitic porous carbons: (1) high-temperature chemical vapor deposition (CVD) [148], (2) high-temperature or/and high-pressure treatment of carbon precursors [149,150], and (3) catalytic graphitization [151][152][153]. Catalytic graphitization process in the presence of various catalysts, such as Ni, Co, and Fe, is much more popular strategy because they can be carried out at lower temperatures (~900 °C).…”

Catalytic Graphitization of Cellulose Using Nickel as Catalyst

“…Hoekstra pyrolyzed microcrystalline cellulose spheres homogeneously loaded with base metal salts (nitrates of nickel, cobalt, and iron) under N2 atmosphere in the temperature range from 500 to 800 C, and turbostratic graphitic nanoribbons were formed under such conditions . Liu prepared activated carbon with 3 to 8 ultra-thin graphitic layers using leaves of Zizania latifolia as a starting material at 900 °C with the assistance of Ni; in that study, approximately 30 graphitic layers were observed when the heating temperature was increased to 1000 °C (Liu et al 2013).…”
