Templated sol-gel Sr2TiO4 nanoparticle preparation as photocatalyst: Morphological-depended efficiency in organic dyes degradation

چکیده مقاله

semiconductor photocatalysts can effectively break down organic dye pollution. the degradation of congo red and methylene blue by photocatalysis using a perovskite sr2tio4 nano-photocatalyst was investigated in this work. the nanostructure preparation method and template on photocatalytic efficiency were investigated. results showed a correspondence of efficiency and procedure-based morphology. the catalyst was then examined using xrd, bet, ft-ir, sem, and tga/dta. under uv light irradiation, the sr2tio4 nanoparticle’s photocatalytic activity was assessed. at room temperature, 5 ppm of sr2tio4 nano-photocatalyst dose, 50.0 mg/l initial dye concentration, and 60 minutes of irradiation time, degradation efficiencies of 94.0% for congo red and 97.0% for methylene blue were attained. this photocatalyzed reaction exhibits a first-order behavior. for congo red and methylene blue, the degradation rate constants were investigated. the investigation demonstrated that sr2tio4 nano-photocatalyst offers a high potential for methylene blue and congo red photocatalytic degradation.
