Abstract This study demonstrates the potential of Fe-doped BiVO 4 as an efficient photocatalyst for degradation tetracycline (TC). The was synthesized using hydrothermal method, resulting in a monoclinic heterostructure with crystallite size ranging from 27.37 to 29.10 nm and optical band gap 2.69–2.87 eV. Photocatalytic tests revealed that 3 wt% Fe doping exhibited highest efficiency, removing 73.37% TC 120 min under low-power (13 W) UV lamp. enhanced photocatalytic performance attributed improved electron–hole separation optimized concentration, which facilitated more light absorption charge carrier dynamics. Additionally, antibacterial confirmed catalyst’s ability inactivate Staphylococcus aureus , even absence light, demonstrating its dual functionality both pollutant bacterial inactivation. cost analysis costs RM 8.17 per gram, further enhancing appeal scalable cost-effective applications. These findings highlight versatility addressing antibiotic-based pollution waterborne pathogens, making it promising candidate practical applications wastewater treatment environmental remediation. contribute global efforts mitigating antibiotic microbial pollution, particularly regions where access high-energy technologies is limited.
