The BET surface area analysis was conducted to evaluate the surface characteristics of the synthesized photocatalysts, utilizing both Langmuir and BET plot analyses to obtain reliable results. The analysis revealed that the pore size and pore volume of the materials fell within the desired range, indicating suitable structural properties for photocatalytic applications. The outgassing process was performed for a duration of 6 hours to ensure the removal of any adsorbed moisture or impurities prior to the analysis.
