Synthesis and characterization of γ–alumina nanospheres templated by lauric acid

Abstract

A novel route for the synthesis of alumina nanospheres was reported by a surfactant-governed approach in the presence of lauric acid. The products were characterized using X-ray diffraction (XRD), scanning electron microscope (SEM) and N 2 adsorption-desorption techniques. The results show that the produced alumina nanospheres possess uniform nanosphere sizes ranging from 80-120 nm, and high surface area of 550 m 2/g. It suggests that the synthesized alumina nanospheres are formed through self-assembly of surfactant/alumina species complex in 1-propanol system.
