Molybdenum Trioxide Microrods synthesized with Corn Straw as Biological Templates and its Electrochemical Performance in Aqueous Battery

Abstract

In this paper, MoO3 microrods was 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 was studied．The results show that the MoO3 material synthesized by template method is Orthorhombic structures．And 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 mAh/g at a scanning rate of 1mv/s, which showing good capacity and cycling performance.
