Effect of Vitamin C Template on Morphology and Structure of α–Alumina

α- Alumina, a stable alumina polymorph, is usually formed by heat treatment of other polymorphsat temperatures higher than temperatures above 1000 C, leading to severe surfacearea loss [1]. Nano α-Alumina particles can be utilized in polymer composites, paints, varnishes,coatings, in order to strengthen their mechanical properties. Furthermore, highstrength ceramics can be produced from Nano α-Al2O3 powders at reduced temperatures [2].In this research, α-Alumina powder was prepared via hydrolysis of aluminum isopropoxide,as inexpensive precursor, in the precence of vitamin C (as a chiral pool and a co-structuraldirecting-agent) in a facile and green procedure (Fig. 1). The influence of vitamin C and itsdegradation products on the texture and morphology of alumina was investigated by themeans of XRD, SEM, TEM, EDX, BET, N2 adsorption–desorption isotherm and optical rotation.The distinctive feature of this research is obtaining fine alpha-alumina with size less than30 nm through a facile and green synthetic procedure using Vitamin C template-controlledpore size. Tthe surface area witnessed a significant fall with an increase of Vitamin C molarratio.
