Effect of Strontium Substitution on the Tribocatalytic Performance of Barium Titanate

This study investigates the impact of Sr doping on the tribocatalytic performance of BaTiO(3) in degrading organic pollutants. Ba(1-x)Sr(x)TiO(3) (x = 0–0.3) nanopowders are synthesized and their tribocatalytic performance evaluated. By doping Sr into BaTiO(3), the tribocatalytic performance was enhanced, resulting in an approximately 35% improvement in the degradation efficiency of Rhodamine B using Ba(0.8)Sr(0.2)TiO(3). Factors such as the friction contact area, stirring speed, and materials of the friction pairs also influenced the dye degradation. Electrochemical impedance spectroscopy revealed that Sr doping improved BaTiO(3)’s charge transfer efficiency, thereby boosting its tribocatalytic performance. These findings indicate potential applications for Ba(1-x)Sr(x)TiO(3) in dye degradation processes.
