Electrical and electrochemical properties of tungsten carbide

Abstract

Modified polymer precursor method was used to synthesized Tungsten carbide (WC). The formation of WC was ascertained through X-ray Diffraction (XRD) and Thermo Gravimetry Analysis (TGA). The WC electrode was synthesized over 316 stainless steel to evaluate electrical conductivity by four probe method and electrochemical performance through cyclic voltammetry (CV). The CV curves of WC electrode were found in the potential span of -1.5 to 0.0V in KOH (1.0M). The WC electrode exhibit band gap of 0.64 eV and good cyclic stability over 200 cycles.
