Since the current study primarily focused on UV-A light, expanding the scope to include visible light and sunlight irradiation is crucial. Visible light-responsive photocatalysts have significant practical advantages, as sunlight is a sustainable and abundant energy source. Testing the tri-doped catalysts under simulated solar light would provide a more comprehensive understanding of their performance and applicability for environmental remediation. Incorporating field-scale experiments could also help assess their real-world efficacy, considering factors such as light intensity variations, water flow rates, and the presence of competing substances in wastewater.
