摘要

The activity and stability of Cu nanostructures strongly depend on their sizes, morphology and structures.Here we report the preparation of two-dimensional(2 D) 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(1 D) 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 I_(ON)/I (OFF) ratio(>2.7 × 10~3).
