Synthesis and Electrochemical Performance of Tungsten Carbide

: Tungsten carbide (WC) was synthesized via modified polymer precursor method. The formation of WC was ascertained through Fourier-transform infrared spectra (FT-IR), x-ray diffraction (XRD), thermogravimetry analysis (TGA) and differential thermo analysis (DTA). The WC electrode was synthesized over 316 stainless steel to evaluate electrochemical performance through cyclic voltammetry (CV). The CV curves of WC electrode were found in the potential span of -0.6 to 0.0V in KOH (1.0 M). The WC electrode shows specific capacitance (Cs) of 110 F/g at 0.001 V/s and good cyclic stability over 500 cycles.
