Synthesis of Cupric Particles Induced by X-ray Radiolysis

Abstract

The X-ray radiolysis-induced-synthesis of copper and cupric oxide particles in an aqueous copper sulfate (CuSO₄) solution with additive ethanol has been investigated. An X-ray irradiation allows for the synthesis of copper and cupric oxide particles and their aggregation into clusters. The morphology and composition of these particles were characterized by scanning electron microscope with energy dispersive X-ray spectroscopy, X-ray diffraction measurement and micro-Raman spectroscopy. The cupric oxides are considered to be consisting of CuO, Cu₂O and Cu₄O₃. The additions of acetone and acetic acid are unable to synthesize any particles. The synthesis of copper and cupric oxide particles sheds light on fabrication of three-dimensional patterning made of composite materials.
