The catalyst was then implemented to decompose the antibiotic tetracycline (TC) in water under visible light. The outcomes revealed that the degradation rate of TC reached 97.69 % using NiO/TiO₂, which is substantially greater than the degradation achieved with pure NiO (52.43 %) and TiO₂ (71.11 %) within a 48-minute period pursuant to the most favorable circumstances.
