In this work is described a means of improving the chemical stability of Cu₂O@SiO₂, Cu₂O@SnO₂ and Cu₂O@TiO₂ materials. The SiO₂, SnO₂ and TiO₂ 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 Cu₂O were characterized using transmission electron microscopy and X-ray diffraction.
