One-step sonochemical synthesis of Zn(OH)_2/ZnV_3O_8 nanostructures as a potent material in electrochemical hydrogen storage

摘要

This paper reports for the first time the synthesis of polyhedral-like Zn(OH)_2/ ZnV_3O_8 nanostructures by a single-step sonochemical method. Particle formation and growth were controlled by using hydrazinium hydroxide and ethylenediamine under ultrasonic waves and then acidifying the medium. After synthesis and identification by XRD, EDS, and FESEM techniques, the mentioned nanostructures were used for electrochemical hydrogen storage, which showed a high potential of 3300 mAh/g storage. Metal hydroxides and multi-valent ions such as vanadium are highly capable of electrochemical processes, so this paper focuses on their synthesis.
