Abstract

A novel meosoporous tubular Co₃O₄ has been fabricated by a simple and cost-effective biomorphic synthesis route, which consists of infiltration of cotton fiber with cobalt nitrate solution and postcalcination at 673 K for 1 h. Its electrochemical performance as a supercapacitor electrode material is investigated by means of cyclic voltammetry and chronopotentiometry tests. Compared with bulk Co₃O₄ prepared without using cotton template, biomorphic Co₃O₄ displays 2.8 fold enhancement of pseudocapacitive performance because of the unique tubular morphology, relative high specific surface area (3 and 0.8 m2/g for biomorphic Co₃O₄ and bulk Co₃O₄, respectively), and mesoporous nature.
