Abstract EN
The deposition of copper (Cu) and cupric oxide (Cu4O3, Cu2O, and CuO) particles in an aqueous copper sulfate (CuSO4) solution with additive alcohol such as methanol, ethanol, 2-propanol, and ethylene glycol has been studied by X-ray exposure from synchrotron radiation.
An attenuated X-ray radiation time of 5 min allows for the synthesis of Cu, Cu4O3, Cu2O, and CuO nano/microscale particles and their aggregation into clusters.
The morphology and composition of the synthesized Cu/cupric oxide particle clusters were characterized by scanning electron microscopy, scanning transmission electron microscopy, and high-resolution transmission electron microscopy with energy dispersive X-ray spectroscopy.
Micro-Raman spectroscopy revealed that the clusters comprised cupric oxide core particles covered with Cu particles.
Neither Cu/cupric oxide particles nor their clusters were formed without any alcohol additives.
The effect of alcohol additives is attributed to the following sequential steps: photochemical reaction due to X-ray irradiation induces nucleation of the particles accompanying redox reaction and forms a cluster or aggregates by LaMer process and DLVO interactions.
The procedure offers a novel route to synthesize the Cu/cupric oxide particles and aggregates.
It also provides a novel additive manufacturing process or lithography of composite materials such as metal, oxide, and resin.
