The particle size of photocatalysts is a determinant factor in their photocatalytic activity. Smaller particles typically offer a larger surface area to volume ratio, which translates to more active sites for the adsorption of reactants and the subsequent photocatalytic reactions. Additionally, the particle size can influence the light absorption properties and the diffusion of reactants and products, which are critical for the photocatalytic process. The five photocatalysts, designated as (1B 0.1CE 0.06AG), (1B1CE0.06AG), (2B 0.1CE0.06AG), (2B 1CE 0.06AG), and (1B 1CE 0.1AG), represent a range of doping configurations. Each configuration is tailored to optimize specific properties of the photocatalyst, such as light absorption, charge carrier separation, and reactivity.
