Solid state synthesis of copper tungstate nanoparticles and its electrochemical detection of 4-chlorophenol

Copper tungstate (CuWO4) nanoparticles were prepared by Solid state synthesis. The CuWO4 nanoparticles were synthesized by reacting 1:1 mole ratio of copper chloride and sodium tungstate. The XRD pattern reveals that the synthesized CuWO4 has anorthic (triclinic) structure. In addition, the average grain size, lattice parameter values were also calculated using XRD data. The FT-IR analysis confirm the presence of Cu-O and W-O bonds in CuWO4 nanoparticles. The electrochemical sensing behavior of CuWO4 nanoparticles towards 4-chlorophenol was investigated using cyclic voltammetry.
