Summary:In this work is described a means of improving the chemical stability of Cu O@SiO , Cu O@SnO and Cu O@TiO materials. The SiO , SnO and TiO coated samples were stable from pH 3 to pH 10 for up to seven days. To determine the stability of the coated nanoparticles, and their colloidal solutions under acidic and basic conditions, colloidal nanoparticle solutions with various pH values were prepared and monitored over time. Details of the effect of variations in pH on the phase stability of core-shell type Cu O were characterized using transmission electron microscopy and X-ray diffraction.
