Pure lead nanoparticles with stable metallic surfaces, on perovskite lead strontium titanate particles.
We demonstrate an efficient method of fabrication for pure lead nanoparticles with non-oxidized surfaces, supported on perovskite lead strontium titanate particles with a size distribution from tens to several hundreds of nanometers. The fabrication method is based on co-precipitation and subsequent annealing in air at 600 degrees C. Transmission electron microscopy revealed that the pure lead nanoparticles show structural fluctuations under intense electron-beam irradiation, like gold and platinum nanoparticles.
