Ordered honeycomb-like network of MnO2 center dot nH(2)O nanocrystals formed on the surface of a Mn(OAc)(2) solution drop upon interaction with O-3 gas

摘要

Planar ordered honeycomb-like structures of the MnO2 layered birnessite-type crystalline form have for the first time been synthesized on the surface of Mn(OAc)(2) solution drops upon interaction with O-3 gas. The obtained network consists of 2D nanocrystals of the thickness up to 10 nm. The prepared material possesses a hierarchical structure and can be used in a fabrication of advanced sensor and electrode materials.
