A new synthesis of ultrafine nanometre-sized bismuth particles

摘要

A new synthesis of Bi(0) nanoparticles is reported. A low temperature solution phase reduction of BiCl_3 with t-BuONa activated sodium hydride at 65 deg C has been successfully used to prepare large quantities of colloidal Bi(0) nanoparticles with a diameter in the range 1.8-3.0 nm. The resulting Bi nanoparticles were characterized using transmission electron microscopy, XPS analysis and x-ray powder diffraction.
