Abstract: Using coal tar pitch based amphiphilic carbonaceous materials (ACMs) as the
precursor and amphiphilic triblock copolymer Plutonic P123 as the only soft template, carbon
nanospheres with partially ordered mesopores and hollow carbon nanofibers were synthesized.
The concentration of P123, cp, and the mass ratio of P123 to ACM, r, are the key parameters of
controlling the shape of the as-prepared products. Mesoporous carbon nanospheres with
diameter of 30-150 nm were prepared under the condition of cp = 13.3 g/L and r = 1.2. When cp
= 26.7 g/L and r = 2, hollow carbon nanofibers with diameters of 50-200 nm and
mesopores/macropores were obtained. Carbon nanospheres and hollow carbon fibers were
amorphous materials. The mesoporous carbon nanospheres show good stability in the cyclic
voltammograms and their specific capacitance at 10 mV s-1 is 172.1 F/g. © 2013 Elsevier B.V. All
