Synthesis, characterization and lithium-storage performance of MoO2/carbon hybrid nanowires

Abstract

This paper presents a novel strategy to synthesize MoO₂/carbon nanowires based on organic–inorganic hybrid nanocomposites with nanometre periodic structures. The organic–inorganic hybrid precursors provide uniform reactions throughout the composites for achieving novel carbon-hybrid structures and nano-morphology via easy calcination. Through the systematic physical characterization including scanning electron microscopy, transmission electron microscopy, X-ray powder diffraction, X-ray photoelectron spectroscopy, Raman spectroscopy, etc., the one-dimensional and carbon-hybrid structure of MoO₂/C nanowires was confirmed. This synthetic strategy is also proved universal for other novel MoO₂/C nanostructures based on various organic-inorganic hybrid precursors. Furthermore, the MoO₂/C hybrid nanowires show good rate capability even at the high current density of 1000 mA g⁻¹ as anode material for lithium ion battery.
