Nanosheets: Rapid and Up-Scalable Fabrication of Free-Standing Metal Oxide Nanosheets for High-Performance Lithium Storage (Small 17/2015)

Free-standing α-Fe2O3 nanosheets, SnO2 mesoporous nanosheets, and sandwich-like polyaniline (PANI)/SnO2/PANI nanosheets are fabricated under very mild conditions by Y. Yu and co-workers using a facile galvanic replacement method. During the fabrication, δ-MnO2 nanosheets are used as oxidants and templates, Fe2+, Sn2+, and aniline are employed as reductants and precursors of target products, realizing the rapid and up-scalable fabrication of various nanosheets. On page 2011, these nanosheets show a high rate capability and long-term durability as anodes for Li-ion batteries.
