Synthesis and characterization of MgZnCo ternary mixed metal oxide by the sonochemical method for solid hydrogen storage

Abstract

In the present investigation, MgZnCo ternary nanocomposites were developed via a one-step sonochemical technique. The nanocomposite was characterized using structural and optical methods. The formation of different crystalline nanocomposite phases (MgO, ZnO, and Co3O4), and a binary phase (Mg-Zn) has been confirmed by X-ray diffraction. Also, it was indicated that varying of Co molar ratio had an impact on the average sizes of the nanoparticles. SEM showed octahedron-shaped nanoparticle morphology with different average sizes for the nanocomposites prepared. Photoluminescence analysis showed the presence of green and ultraviolet emissions, with green luminescence bands being most often observed. with the intention of discovering samples with suitable structural and optical properties for future solid hydrogen storage applications.
