Abstract
A simple and cost-effective method for preparing copper particles is reported, which has the ability to shape the particle without using any capping agent or hard template. These samples were characterised by a variety of techniques, such as scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray detector and UV-vis spectrometer. In the synthetic procedure, the reaction temperatures and surfactant content exerted a strong influence on the shape of copper particles. In addition, the shapes of copper particles play an important role in UV-vis absorption and electrical conductivity properties. The absorption spectrum and electrical conductivity of copper particles showed obvious difference, which suggests the possible assembly of novel photocatalysts and high electrical conductivity functional materials.
