Ultrasonochemical-Assisted Synthesis of CuO Nanorods with High Hydrogen Storage Ability

Abstract EN

Uniform CuO nanorods with different size have been synthesized in a water-alcohol solution through a fast and facile ultrasound irradiation assistant route.

Especially, the as-prepared CuO nanorods have shown a strong size-induced enhancement of electrochemical hydrogen storage performance and exhibit a notable hydrogen storage capacity and big BET surface area.

These results further implied that the as-prepared CuO nanorods could be a promising candidate for electrochemical hydrogen storage applications.

The observation of the comparison experiments with different concentrations of NaOH, ethanol, CTAB, and HTMA while keeping other synthetic parameters unchanged leads to the morphology and size change of CuO products.
