Self-catalyzed growth of ruthenium oxide nanoplates

Fig. 1. (a) Nanoplates (60~nm) of RuO2, (b, c) top view of plates with varied growth morphology, (d) cross-sectional view of nanoplate stacks, (e) top-view of nanoplates showing uniform growth morphology, (f) bottom layer of a continuous film of RuO2.

Nanometer-sized RuO2 materials with controlled shapes and dimensions have been synthesized by low-pressure chemical vapor deposition system. Transition metal oxides such as ruthenium oxide can be used as electrodes for lithium-ion batteries. The images to the right revealed that by carefully controlling deposition parameters nanostructured materials with control shapes and dimensions can be deposited by gas phase  deposition processes.
