Abstract

Due to the wastewater crisis, tungsten (W)-doped ZnO particles were synthesized with varying W dopant concentrations using the co-precipitation method for the enhancement of photocatalysis application, which can reduce the wastewater crisis by the degradation of pollutant molecules occurring by its process. The crystalline and optical properties of the synthesized powders were analyzed by various methods as well as photocatalytic performance. Among all conditions, the WZ-5 sample exhibited the lowest band gap energy at 3.11 eV and the highest photocatalytic efficiency, achieving 98.16% degradation within 60 minutes. These results demonstrate that tungsten doping can effectively enhance ZnO photocatalytic activity by promoting better charge carrier separation and extending light absorption, especially in the visible region, making W-doped ZnO a promising material for wastewater treatment applications.
