Fabrication of ruthenium metal nanosheets via topotactic metallization of exfoliated ruthenate nanosheets

摘要

The metallization behavior of molecularly thin RuO_2 nanosheets obtained from complete delamination of layered ruthenates was studied. Interestingly, the RuO_2 nanosheets in a monolayer state topotactically transformed into a single layer of Ru atoms, i.e., ruthenium metal nanosheets, which can be regarded as a new family of nanosized metals.
