Abstract
Lead carbonate nanoparticles were synthesized via chemical co-precipitation method from lead (II) nitrate and sodium carbonate. The formed nanoparticle is characterized by powder x-ray diffraction, scanning electron microscopy, ultra-violet spectroscopy and fourier transform infrared spectroscopy, confirmed the preferential growth of lead carbonate nanoparticles that width is 44.78 nm. The SEM image shows the synthesized lead carbonate show well crystallized particles with rod shaped morphology. The FTIR spectrum is used to study the stretching and bending frequencies of molecular functional groups in the sample. From UV spectrum, the band gap of lead carbonate nanoparticles is found to be 4eV.
