This research delves into the properties of x% ZW-BT compounds (x=3% and 7%), synthesized using a solid-state reaction approach. Utilizing X-ray diffraction, the crystal structure of the x% ZW-BT compositions is confirmed, showcasing a distinct tetragonal symmetry devoid of any parasitic phases. With increasing dopant concentrations, slight reductions in lattice parameters are observed, signifying the even diffusion of dopant (Zn2+ and W6+) ions. Moreover, the validation of metal-oxygen bonding vibrations is achieved through Fourier-transform infrared spectroscopy (FTIR) analysis. Scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDX) reveals consistent granular arrangements and clear elemental signatures in both compositions. Notably, photocatalytic experiments highlight remarkable degradation rates; within 100 minutes, 3% and 7% ZW-BT achieve degradation levels of 78.04% and 88.9% respectively. These findings underscore the significant potential of these compounds for environmentally friendly photocatalytic applications.
