For instance, the photocatalyst (1B 0.1CE 0.06AG) contains a lower concentration of CE compared to (1B 1CE 0.06AG). This difference in doping levels can lead to variations in the electronic properties and, consequently, the photocatalytic activity. Similarly, increasing the amount of B from 1B to 2B, as seen in (2B 0.1CE0.06AG) and (2B 1CE 0.06AG), can alter the lattice structure and the number of active sites.
