Synthesis of Sodium-vanadate-doped Ordered Mesoporous Carbon Foams as Capacitor Electrode Materials

Sodium-vanadate-doped ordered mesoporous carbon foams (V-MCFs) were prepared through an evaporation-induced self assembly strategy. The resultant V-MCFs exhibit highly ordered mesostructure with specific surface areas of 714 m(2) g(-I) and uniform pore sizes of 4.1 nm. The surface wettability and graphitization degree of V-MCFs were increased due to the incorporation of sodium vanadate into the carbon matrix. Besides, sodium vanadate brings a pseudo-capacitive effect in V-MCFs. V-MCFs thus exhibit higher capacitance and fast charge-discharge properties compared with pure mesoporous carbon foams.
