| Abstract: | The activity and stability of Cu nanostructures strongly depend on their sizes, morphology and structures. Here we report the preparation of two-dimensional (2D) Cu@Cu-BTC core-shell nanosheets (NSs). The thickness of the Cu NSs could be tuned to sub-10 nm through a mild etching process, in which the Cu-BTC in situ grow along with the oxidation on the surface of the Cu NSs. This unique strategy can also be extended to synthesize one-dimensional (1D) Cu@Cu-BTC nanowires (NWs). Furthermore, the obtained Cu@Cu-BTC NSs could be applied as an effective material to the memory device with the write-onceread-many times (WORM) behavior and the high ION/IOFF ratio (>2.7×103). |
