Synthesis and applications of nano aluminum dioxides

Abstract

This review provides an overview of aluminium dioxide nanoparticles' synthesis, characterization,and applications in various methods. Aluminium dioxide is the main class of nanometal oxides used in different applications depending on the properties of the particles, which can control many chemical processes such as in imaging, catalysis, and environmental and medical applications. The reactivity of aluminum dioxide is mostly a candidate for various mechanical and energy research. It is noticed that the most abundant aluminum dioxide type is α- Al2O3 due to its higher density than other aluminum dioxide phases. Fabricating aluminum dioxide with a relatively small distribution has significant advantages in controllable deposition applications. It can give a highquality surface area with small particle sizes, which favors forming films and catalytic activity. There is a broad range of methods to synthesize metal oxides, but the most widely used method is based on less time-consuming processes and green condition systems.
