摘要：

From platelets to sheets: A topochemical phase conversion employing bromine in acetonitrile transforms β-Co(OH)2 into monometallic Co 2+-Co3+ layered double hydroxide (LDH) with a Co 2+/Co3+ ratio of 2:1 (see the elemental maps of Co, Br, and O in a Br--intercalated Co2+-Co3+ LDH platelet). Further treatment allows exfoliation of Co2+-Co 3+ LDH into positively charged Co(OH)2 nanosheets. Scale bars: 2 μm. (Figure Presented). © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
