Carbon materials have been obtained by the chlorination reaction of Ti(C5H5)Cl-2 at 900 degrees C, varying the reaction time at 30, 60, 90 and 120 min. The average microstructure, studied by X ray powder diffraction, suggest that these materials consist mainly of disordered carbon with low graphitization degree (from 13.5 to 16.5%). These results are in agreement with the Raman data since the D band (at approximate to 1350 cm(-1)) indicates that disordered carbon networks have appeared. The calculated in-plane correlation length increases from 4.04 to 4.70 nm as the chlorination time increases from 30 to 120 min. The textural analyses reveal adsorption isotherms type 1 with hysteresis H4, microporous areas as high as 855 m(2)/g and pore volume of 0.55 cm(3)/g. Additionally, an important contribution of mesoporosity, around 3.6 nm, was also detected. (C) 2015 Elsevier B.V. All rights reserved.
