Abstract
The effect of different acids such as cinnamic acid, salicylic acid, and oxalic acid on size, morphology and uniformity of PbTiO3 nanoparticles prepared via a auto-combustion sol–gel route was investigated. The structural, morphological, and optical properties of as-obtained products were characterized by techniques such as electron dispersive X-ray spectroscopy, X-ray diffraction, scanning electron microscopy and ultraviolet–visible spectroscopy. The estimated band gap shows that this product may be used as a photocatalyst, so the photocatalytic test was performed by photooxidation of methyl orange under UV irradiation and in the presence of PbTiO3. The results showed that methyl orange degradation was about 95% under for 50 min, so the synthesized product can be used as an effective photocatalyst. Vibrating sample magnetometer was used to study the magnetism properties of PbTiO3 sample.
