Antibacterial and photocatalytic properties of Ag-doped CeO₂:BaO synthesized by simple solution combustion method

Ag-doped CeO2:BaO (ACBO) composite was synthesized by the simple solution combustion approach and investigated for its antibacterial and photocatalytic properties. CeO2 was doped with Ag 0.0-2.0 wt% as a part of the ACBO composite. Best antibacterial activity (ZOI = 13 mm) was measured against Bacillus by ACBO with 2.0 wt% Ag among the Pseudomonas, Bacillus, Staphylococcus and E. coli in comparison to Ciprofloxacin. Photocatalytic action against the methyl blue (598 nm) was also inspected, and a maximum degradation efficacy of 76% for the 2.0 wt% ACBO was observed in 16 min.
