Preparation of PbO nanocrystals via decomposition of lead oxalate

The present study reports the preparation and characterization of PbO nanocrystals obtained via a thermal decomposition route. The PbO nanocrystals were synthesized using lead oxalate powder as a precursor. Nanostructured products were investigated by means of XRD, TEM, FT-IR and XPS. The XRD results indicate that tetragonal phase β-PbO with a particle size of about 30–45 nm was obtained when the intermediate precipitate was calcined at 500 °C.

Graphical abstractThe present investigation reports on the synthesis of PbO nanocrystals using thermal decomposition, and its physicochemical characterization. PbO nanocrystals have been prepared using lead oxalate powders as a precursor. The results indicated that the orthorhombic phase β-PbO with a particle size of about 30–45 nm was obtained when the calcination temperature was 500 °C.Figure optionsDownload full-size imageDownload as PowerPoint slide
