Abstract: γ-Al2O3 is one of many types of alumina. It has a series of remarkable characteristics, such as porosity, large specific surface area, high activity, and good thermal stability. Therefore, γ-Al2O3 is often used as adsorbents, catalysts and catalyst carriers, and has extremely wide applications in petrochemical, environmental protection and other fields. In industrial design, due to the different physical properties of γ-Al2O3, it is often widely used in different design products. In this work, aluminium nitrate and glycine were used as raw materials, and nano-γ-Al2O3 was synthesised by low-temperature combustion synthesis. XRD and TEM test methods were used to analyse and characterise the reaction products, investigate the pH value of the solution, the molar ratio of the reactants, the calcination temperature, and the calcination time on the formation, particle size, crystal transformation and morphology of the reaction product and other aspects. The paper obtains relevant data through experiments, and hopes to be widely used in industrial design.
