This presentation details the synthesis and characterization of gold-decorated alkaline earth barium titanate (BTO) nanoparticles. BTO nanoparticles were synthesized using a low-temperature sol-gel method. X-ray diffraction (XRD) patterns confirmed the cubic structure of the BTO nanoparticles. Furthermore, gold nanoseeds were decorated on the surface of the BTO nanoparticles, and partial gold shells were grown using a simple seeded-growth method. Extinction spectra showed broadening of the extinction band in the visible region due to the localized surface plasmon resonance (LSPR) of the gold nanoparticles. Additionally, photoluminescence spectra indicated a decrease in electron-hole recombination of the BTO nanoparticles in the presence of gold on the surface. Studies of the use of these nanoparticles in visible light-driven water-splitting photocatalytic reactions will be described.
