It was shown for the first time that open microspheres 1–10 µm in size with Cu(OH)2 walls and unique morphology are formed as reactions of rapid hydrolysis of copper (II) cations when microdroplets of aqueous CuSO4 solution are sprayed on the surface of alkaline solution of Na2SO4 at room temperature and without the use of surfactants. It has been shown that the microspheres formed under these conditions have a single hole in their walls with a size ranging from fractions to units of a micrometer and they are oriented on the surface of the alkaline solution with this hole facing towards the air. These microspheres can be transferred to various substrates using a vertical elevator technique, where they are deposited in layers with their holes predominantly oriented in the opposite direction from the substrate. It has been found that the walls of these microspheres are several hundred nanometers thick and are composed of a combination of Cu(OH)2 nanocrystals, and nanorods, with a diameter 5–10 nm and a length up to 500 nm. When the samples are heated in air at 150°C, these nanocrystals lose water and form CuO single crystals without significant changes in their morphology. It was found that applying layers of microspheres to the surfaces of various substrates gives it superhydrophilic properties.
