Abstract

An efficient fabrication method for pure lead nanoparticles supported on lead-based perovskite particles has been developed using co-precipitation. The annealing of the co-precipitates in air at 600Â°C produced lead nanoparticles with non-oxidized and non-contaminated surfaces. High-resolution transmission electron microscopy revealed that the pure lead nanoparticles with an average size of ~4 nm showed structural fluctuations under an intense electron beam irradiation, similar to gold and platinum nanoparticles. This result implied that the lead nanoparticles prepared by this co-precipitation process are expected to be used as catalysts.
