N2 - It was shown for the first time that open microcapsules 1–5 μmin size with Mn3O4 walls and unique morphology are formedas a result of spraying an aqueous MnSO4 solution onto thesurface of an alkali solution. The walls have a thickness of80–120 nm and consist of an array of Mn3O4 nanosheets witha thickness of 2–3 nm, oriented predominantly in the radialdirection towards the center of the microcapsule. There is aspecial rim with a height of 100–200 nm around the hole of themost microcapsules, which can be a kind of ‘ground’ whenfixing such microcapsules on the surface of a substrate in theprocess of application by the Langmuir–Schaefer technique.
