Microrods synthesized of MoO3 with corn straw as biological templates and its electrochemical performance in aqueous aluminum-ion battery

Abstract

ABSTRACT. In this paper, MoO₃ microrods were prepared using corn straw as biological template via roasting process The components and crystal characterization of the material were investigated via X-ray diffraction (XRD)，scanning electron microscopy (SEM), and the electrochemistry property and mechanism were studied. The results showed that the MoO₃ material synthesized by template method is orthorhombic structures. The MoO₃ particles were submicron and micron rods with uniform distribution and a smooth surface. MoO₃ microrods had an average diameter that ranged from 1 to 2 μm. The result indicated that the MoO₃ as the new negative of aluminum battery delivers a higher discharge capacity of 190 mA·h·g^-1 at a scanning rate of 1 mV·s^-1, which showing good capacity and cycling performance.
