Structure, morphology and electrochemical properties of SrTiO3 perovskite: Photocatalytic and supercapacitor applications

In order to explore an alternative photocatalyst for environmental remediation, we report the sol-gel process for the synthesis of strontium titanate (SrTiO3) nanoparticles (STNPs). The as-synthesized STNPs were found to poses cubic perovskite-type crystal structure with an average crystallite size...
