Recent Progress on the Production of Aluminum Oxide (Al2O3) Nanoparticles: A Review

Abstract

This study aims at discussing several methods to produce aluminum oxide (Al2O3) synthesis methods along with the advantages and disadvantages of each method used. In general, several methods are available: (1) precipitation, (2) combustion, (3) sol-gel, (4) wet chemical, (5) synthesis in supercritical water conditions, (6) microwave, (7) mechanochemical, and (8) hydrolysis, and the most efficient method for synthesizing Al2O3 is precipitation because it is facile and the simplest method (compared to other methods), can be proceeded using inexpensive raw materials, produces less pollution, and has several advantages: high purity product, high thermal stability, nearly homogeneous nanoparticle in size, and control desired particle size. The results of the study help to provide comparisons in producing various Al2O3 synthesis methods.

Comprehensive Review of Nanoparticles Dispersion Technology for Automotive Surfaces

“…Chinglenthoiba, Ramkumar [5] reviewed the methods of nanocoating, including physical vapour deposition (PVD), chemical vapour deposition (CVD) and atomic layer deposition (ALD).…”

“…The nanomaterial is a material with any internal or external structures on the nanoscale dimension. The possibility of new physical properties and applications of nanomaterials exists only when nanostructured materials are made available with the desired size, shape, morphology, crystal structure, and chemical composition [4], [5]. Nanostructures are structures that range between 1 nm (molecular scale) and 100 nm in at least one dimension.…”

Fabrication of carbon nanotube (CNTs)/Co3O4-Ni3O4/Al2O3 nanocomposite catalyst and its application for photocatalytic removal of Celestine blue dye

“…Alumina oxide considers as an important supported catalytic material, due to its high surface area, and it is an inert material so that it is widely used as a supported catalyst in heterogeneous catalysis. Its role in catalytic activity arises from it high surface area that prevent agglomeration of particles of catalyst and enhancement of catalytic activity for the catalytic process [21][22][23].…”

Bibliometric Analysis of Aluminium Oxide Nanoparticle in Biomedical Applications

“…Al2O3 is one of the most produced nano-sized chemicals, it is even estimated to reach 20% of all nanoparticle materials in 2005. There are various methods of synthesizing Al2O3 nanoparticles, there are precipitation, combustion, sol-gel, wet chemical, synthesis under supercritical water conditions, with microwaves, mechano-chemically, and hydrolysis [5].…”
