“…Since the synthesis of carbon tubes in 1991, nanometric materials with varying morphologies such as nanoribbons, nanorods, nanowires, nanorings, and nanosheets have been attracting increased attention around the world, owing to their unique properties and potential applications. Among the nanostructured families, nanosized MgO and Fe 2 O 3 , both accessible and versatile metal oxides, have been used widely in a variety of applications, including adsorbent, catalyst, refractory materials, cancer therapy, antibacterial, superconductor, battery, gas sensing, and photoelectrochemical performance …”
