The photocatalytic performance was quantitatively assessed, with the highest degradation efficiency of over 92% achieved for the catalyst with the atomic configuration (x=2, y=0.1, z=0.06) after three hours of sunlight irradiation. This performance was attributed to the synergistic effects of the dopants: boron facilitated charge separation, cerium provided additional active sites, and silver enhanced visible light absorption through plasmonic resonance. Furthermore, the ternary doped catalysts exhibited superior disinfection efficiency, highlighting their dual functionality in environmental remediation.
