This paper reports the facile low-temperature synthesis of Cu$_{1-x}$Zn$_x$WO$_4$ nanoparticles by varying the concentration of Zn using solid-state reaction method. The incorporation of various Zn concentrations can alter the valence band energy and enhance the structural, optical and electrochemical properties. The prepared nanoparticles have a triclinic crystal structure with minimum strain. The variation in zinc concentration is shown by the densely aggregated particles in the SEM image. These nanoparticles exhibit strong absorption in the visible region and the bandgap is found to increase with an increase in Zn concentration. The photocurrent density increases with an increase in the concentration of zinc and found to be a maximum of 8.5 $\mu$A cm$^{-2}$ for $x = 0.4$ due to a lower bandgap of 2.65 eV. Finally, it is observed that an optimum zinc concentration promotes improved photocurrent generation.
