Building on the findings of this study, a multi-faceted approach is required to optimize the performance and applicability of tri-doped TiO₂ photocatalysts. Research efforts should focus on improving the catalyst design to enhance light absorption, reduce recombination rates of electronhole pairs, and maximize the degradation efficiency for a broader range of pollutants. Some specific strategies include: Fine-tuning the concentrations of boron, cerium, and silver can further optimize the catalyst's properties. Experimental studies combined with computational modeling can help predict the ideal dopant configurations for achieving the desired band gap and surface characteristics. Controlling the morphology of TiO₂, such as creating nanosheets, nanotubes, or hollow spheres, can increase the surface area and improve light harvesting. These features allow better pollutant adsorption and enhance photocatalytic activity. Coating the catalyst surface with materials like graphene, carbon nanotubes, or conducting polymers can improve charge mobility and reduce recombination. These materials also contribute to broader light absorption, extending the catalyst's activity into the visible spectrum.
