Abstract

We reports the used of palm-oil based carboxylic compound (oleic acid) as capping ligands in synthesizing of 2-dimensional (2D) ZnO nanopellets. With the assistance of oleic acid and scrupulously controlling the reaction time, we showed that 2-dimensional triangular and hexagonal ZnO nanopellets can be grown by using self-made organometallic compound (zinc (II) oleate, Zn(C 18H33O2)2) as single precursor under non-hydrolytic solution. Zn(C18H33O2) 2 is prepared by ion exchange reaction between non-toxic fatty acid compound and ion Zn2+. The controlling process of thermal pyrolysis of precursor is carried out under inert argon (Ar) atmosphere. Time-dependent shape evolution micrograph observed by transmission electron microscopy (TEM) show that the morphologies of ZnO nanopellets can be controlled by annealing duration. The as-prepared ZnO exhibit good crystallinity according to X-ray powder diffraction (XRD) patterns where all the peaks of ZnO nanopellets can be well indexed with standard hexagonal phase of ZnO crystal structure. Hence, this technique is very effective and reproducible in controlling the shape of ZnO semiconductor nanostructures.
