Abstract
This work investigated the photocatalytic-induced degradation of organic dyes in the wastewater using barium titanate (BaTiO3) supported silver (Ag) metal particles. BaTiO3 ceramics were synthesized using a solid-state reaction route. Ag metal was loaded on BaTiO3 particles using silver nitrate and polyethylene glycol reagents at room temperature without heat and light source. Ag-loaded BaTiO3 powder was characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. Ag-loaded BaTiO3 powder showed more degradation of Rhodamine B (RB) dye as compared to BaTiO3 powder. Around 95.05, 94.75, and 94.5 % of RB dye degradation were observed within 180 min under visible light during the first, second, and third photocatalytic cycles. The photon-induced strong surface plasmon resonance (SPR) effect of Ag metal has played a critical role in the induction of visible light photocatalysis in Ag-loaded BaTiO3 powder.
