Article Preview

A templated carbon has been prepared by using a clinoptilolite-Ca mineral as template and furfuralcohol as carbon source. X-ray diffraction (XRD), nitrogen adsorption, scanning electric microscope (SEM) and cyclic voltammetry (CV) are used to analyze the phase composition, pore structure, micro morphology and electrochemical performance. The specific surface area of the templated carbon is 590m2/g and the mesoporosity is high to 63.4%. In H2SO4 medium, due to its rich mesopores, the carbon exhibits a large capacity and a good rate capability. The capacity of the carbon is 174F/g at a scan rate of 5mV/s. When the scan rate increases from 5 to 300mV/s, the capacity of the carbon decreases only from 174 to 144F/g, exhibiting a good rate capability.
