Abstract

Single-crystal α-MnO ₂ nanotubes have been successfully synthesized by microwave-assisted hydrothermal of potassium permanganate in the presence of hydrochloric acid. The growth mechanism including the morphological and crystalline evolution has been carefully studied with time-dependent X-ray diffraction, electron microscopy, and controlled synthesis. The as-synthesized MnO ₂ nanostructures are incorporated in air cathodes of lithium-air batteries as electrocatalysts for the oxygen reduction and evolution reactions. The characterization reveals that the electrodes made of single-crystalline α-MnO ₂ nanotubes exhibit much better stability than those made of α-MnO ₂ nanowires and δ-MnO ₂ nanosheet-based microflowers in both charge and discharge processes. © 2012 American Chemical Society.
