Comparing this result to literature-reported values for TiO₂-based photocatalysts, the surface area falls within the expected range for nanostructured materials, further supporting the reliability of the analysis. However, it is worth noting that higher surface areas are often desirable for photocatalytic applications, as they provide more active sites for pollutant interaction. Strategies such as optimizing synthesis parameters or employing surfactants during preparation could potentially increase the surface area while preserving the photocatalytic enhancements provided by doping.
