MESOPOROUS CARBON, VANADIUM PENTOXIDE, AND PRUSSIAN BLUE FOR ENERGY STORAGE: A PRELIMINARY STUDY

Tóm tắt

In this work, we present a preliminary study on the synthesis, characterization and electrochemical properties of three different nanoscale materials recently synthesized in our lab: mesoporous carbon (MPC), vanadium pentoxide (VPO), and Prussian Blue (PB). These materials were characterized using X-ray diffraction, scanning electron microscopy, cyclic voltammetry, and galvanostatic charge-discharge techniques. The electrochemical measurements revealed different behaviors for energy storage in these materials. The calculated values of specific capacitance for MPC, VPO, and PB at 10 mV s-1 was 149.1, 71.9, and 448.6 F g-1, respectively, which are promising for electrochemical energy storage.
