“…In this sense, the synthesis of the so called shaped carbon nanomaterials (SCNM) has been achieved by using this technique. SCNM are mainly obtained from metallocenes such as ferrocene [7], chromocene [8,9] and derivatives, for instance titanocene or wolfranocene dichlorides [10,11], because their chemical composition provides the carbon source and the catalyst [12]. In this work, we describe the synthesis, and characterisation of porous carbon spheres obtained at 900 ºC by chlorination reaction of metallocenes and derivatives as carbon precursors.…”

Highly porous carbon nanospheres, external diameter ranging from 40 to 240 nm, have been produced from the chlorination reaction of metallocenes and derivatives at 900 °C. Their nanostructure, studied by Raman spectroscopy, consists of highly disordered graphene-like layers with size below to 6 nm. Their textural parameters showed surface area as high as 1320 m2/g and average pore width of 1.1 nm.
