Strontium calcium titanate, Doping , Photocatalytic activity, Solution combustion synthesis, Antibacterial


Unique dielectric properties of strontium titanate and calcium titanate accommodate utilization of the materials in electronic devices. Doping generally alters microstructure and electronic band structure, which influence catalytic performance of the materials. This study aimed at examining photocatalytic activities of SrxCa(1-x)TiO3 (x = 0, 0.25, 0.5, 0.75 and 1) powders synthesized by solution combustion technique. Relationships among chemical composition, microstructure, bandgap, photocatalytic and antimicrobial performance of SrxCa(1-x)TiO3 were also examined. Experimental results revealed that according to the initial compositions single phases of CaTiO3, SrxCa(1-x)TiO3 and SrTiO3 were observed. Sub-micrometer-sized particles, with average specific surface area ranging from 4.2 to 7.4 m2·g-1, were present. Reduction of bandgap energy was evident in the SrxCa(1-x)TiO3 (x = 0.25, 0.5, and 0.75) powders. Attributed to superior specific surface area and minimal bandgap energy, the greatest photocatalytic degradation of methylene blue measured at wavelength close to 660 nm was observed in Sr0.75Ca0.25TiO3. Experimental results also revealed decent antibacterial performance with percent of bacterial colony reduction greater than 90%. The antibacterial results agreed well with the photocatalytic performance.
