The particle size analysis of photocatalysts is a critical step in the validation of the doping process, ensuring that the modifications at the nanoscale are precise and effective. The successful doping of photocatalysts can significantly enhance their performance by altering their electronic, optical, and surface properties, which are essential for various applications, including environmental remediation and energy conversion.The accuracy of doping is paramount, as it determines the distribution of dopant atoms within the host material and directly impacts the photocatalyst's activity. The particle size results falling within the desired range is a strong indication that the doping method employed is both accurate and reliable. This precision in doping ensures that the photocatalysts have the optimal characteristics for their intended use. Doping at the nanoscale presents several challenges, one of which is the potential for agglomeration or coagulation of nanoparticles. This phenomenon can occur due to various factors, including inaccurate mixing, which leads to the formation of aggregates. These aggregates can adversely affect the photocatalyst's performance by reducing the surface area available for photocatalytic reactions and causing inconsistencies in characterization. The degradation analysis is a crucial component of evaluating a photocatalyst's effectiveness. It involves assessing the material's ability to facilitate the breakdown of pollutants under light irradiation. The fact that the degradation results were within the desired range, despite the challenges of nanoparticle coagulation, speaks volumes about the efficacy of the doping method and the quality of the photocatalysts produced.
