Control of shape and size of metal oxide nanostructures and their magnetic and electrocatalytic properties

Abstract

The rational design and synthesis of the metal oxide nanostructures with different morphology, composition, enhanced conductivity, and structure have heightened the attention of many researchers worldwide to fabricate and evaluate the metal oxide-based nanostructured material with promising applications for energy storage and conversion technologies.Controlled growth of nanostructured materials in shape and size directly influences the catalytic performance. Fe, Co, Ni, Mn-based oxide are high in demand for energy storage devices such as batteries, supercapacitors, water electrolysis. The present work focused on the OER catalytic application by metal oxide nanostructures. The metal-air batteries such as Li-ion, Mg/Zn air batteries, etc. are dependent on the high OER activity. An efficient electrocatalyst is required to overcome the sluggish OER kinetics to improve the overall battery efficiency for a better charge/discharge mechanism.The detailed insight of the metal oxide nanostructures has been investigated to develop sustainable materials with enhanced activity in alkaline, neutral, acidic media and long term stability for industrial application, development in energy storage/conversion techniques with facile synthesis, and lost cost fabrication. newline
