Understanding hydrothermal transformation from Mn(2)O(3) particles to Na(0.55)Mn(2)O(4)·1.5H(2)O nanosheets, nanobelts, and single crystalline ultra-long Na(4)Mn(9)O(18) nanowires

Manganese oxides are one of the most valuable materials for batteries, fuel cells and catalysis. Herein, we report the change in morphology and phase of as-synthesized Mn(2)O(3) by inserting Na(+) ions. In particular, Mn(2)O(3) nanoparticles were first transformed to 2 nm thin Na(0.55)Mn(2)O(4)·1.5H...

Sumario:Manganese oxides are one of the most valuable materials for batteries, fuel cells and catalysis. Herein, we report the change in morphology and phase of as-synthesized Mn(2)O(3) by inserting Na(+) ions. In particular, Mn(2)O(3) nanoparticles were first transformed to 2 nm thin Na(0.55)Mn(2)O(4)·1.5H(2)O nanosheets and nanobelts via hydrothermal exfoliation and Na cation intercalation, and finally to sub-mm ultra-long single crystalline Na(4)Mn(9)O(18) nanowires. This paper reports the morphology and phase-dependent magnetic and catalytic (CO oxidation) properties of the as-synthesized nanostructured Na intercalated Mn-based materials.
