摘要
VO2(A) micro-nanostructures have been synthesized via a facile hydrothermal method by hydrolysis of oxidovandium(2+) ethylene glycolate in malonic acid solution. The novel morphologies of VO2(A) could be readily tuned by altering the concentrations of malonic acid and reaction temperature. It is revealed that rnalonic acid played an important role as a structure directing agent helping the alternative formation of VO2(A). Furthermore, their electrochemical properties were investigated, which reveal that the as-prepared VO2(A) nanorods exhibit a relatively higher first discharge capacity than other VO2(A) morphologies.
