Highly monodispersed ZnO nanorods have been synthesized by the hydrothermal approach with polyacrylamide (PAM) as the template and zinc acetate as the zinc source. Most of these synthesized ZnO rods have diameters of 30 nm~200 nm and lengths of 80 nm~15 μm. The structural characterization of ZnO nanorods was carried out by XRD, TG, FTIR, TEM and SEM. nanoZnO rods can be prepared merely by one step reaction using little template. It indicated that this method can be applied to the commercialization of rod-like ZnO preparation technology.

The use of metal oxides in heterogeneous base catalysis has gained a large interest due to their application in many chemical and industrial processes and is environmental friendly. Basic metal oxides are commonly used and their structures, morphology and performance can be modified by method of preparation and thermal activation. In this study, surface modified amphoteric zinc oxide was prepared via hydration-dehydration method and characterised by TGA and FTIR. The basic strength at various temperatures is characterised by FTIR and back titration analyses. The results shows that surface modified zinc oxide has the highest basic strength of 1.453mmolg-1at 400°C making it a relatively good and suitable compound for use in heterogeneous basic catalysis. This result is also supported by FTIR spectra which show possible relationship between the Lewis O2-and increasing basic strength.
