Abstract
Li4Zn3B4O11/Li2B2O4 (LZBO/LBO) nanocomposites with controlled morphologies were fabricated through pechini sol-gel method. The effect of EDTA against various carboxylic acids (as chelating agents) compered in order to investigation shape, size and representative characteristics. To further inspect, the effect gelling agents examined on the synthesis process. The electrochemical process of hydrogen storage in the Li4Zn3B4O11/Li2B2O4 nanocomposites electrode employing the electrodecomposition of KOH electrolyte has been considered by means of galvanostatic charge-discharge method. It seems that multidisciplinary mechanisms for storage function of obtained nanocomposites involve layered structures, distinct morphology, and physical adsorption lead to fantastic hydrogen storage ability. The hydrogen storage capability for two type morphologies of sphere/rod and nanoparticles assess 222/5 and 402/5 mA h/g, respectively. Based on the acquired consequences, Li4Zn3B4O11/Li2B2O4 nanocomposites can be hopeful components to upgrade the hydrogen storage operation through electrochemical procedure.
