Abstract

original image

Sheet materials: Manganese oxide nanosheets and their oriented thin films can be prepared by a bottom-up approach in aqueous solution under ambient conditions (left). Chelation between the manganese species and ethylenediaminetetraacetate (EDTA) ligands results in birnessite-type nanosheets (see micrographs and diffraction pattern). The biomimetic pathway allows simultaneous control of synthesis and morphogenesis by the EDTA chelating agent.
