Abstract

Recently, with the rapid improvement in the field of nanotechnology, tremendous progress has been achieved not only in the preparation and characterization of nanomaterials but also in their various functional applications. It promotes the generous efforts for synthesizing novel materials, developing easy fabrication techniques, reducing the size of particles, improving device performance, and fabricating low-cost nano-devices. One-dimensional (1D) nanofibers of transition metal oxides have been at the forefront of nanotechnology research owing to their fascinating physical properties and potential technological applications in several fields such as biomedical, sensors, and energy-storage devices. Over the last 10 years, various synthesis techniques have been developed to fabricate 1D nanofibers. Among these, electrospinning has been found to be a simple, versatile, cost-effective, and unique technique for mass production of nanofibers with high aspect ratio and reproducibility. This chapter elaborates the effect of different process and system parameters on the morphology of binary MnxOy nanofibers. Furthermore, the electrochemical performance of as-synthesized MnxOy nanofibers is discussed in detail. The MnxOy nanofibric morphology exhibits superior electrochemical performance to nanoparticles and nanorods, which is attributed to the presence of voids, mesoporous and interconnected network of nanoparticles forming fibric morphologies. The chapter describes all the important aspects of fabricating MnxOy nanofibers with highest reproducibility of their electrochemical performance for commercial utilization.
