摘要

A novel dual morphology of MoO3, combining nanorods and nanospheres, was synthesized via a hydrothermal method to enhance its structural and electrochemical properties. X-ray diffraction confirmed the orthorhombic phase with high crystallinity, while field-emission scanning electron microscopy revealed distinct nanorods and nanospheres. The cyclic voltammetry analysis showed a stable cathodic peak without an anodic counterpart, indicating excellent material stability and reduction efficiency. Electrochemical impedance spectroscopy demonstrated a charge transfer resistance of 23,049 Ω and Warburg diffusion impedance of 3604 Ω s–1/2, highlighting efficient electron transfer dynamics. The synergistic effect of nanorods, offering high surface area, and nanospheres, providing structural stability, significantly improved the material’s electrochemical behavior. These properties make dual-morphology MoO3 a strong candidate for solar cells and energy storage devices, offering a novel strategy for optimizing charge transfer and reducing recombination losses in energy materials.
