Abstract:

A novel method for synthesis of pure metal and metal oxide nanocrystals in the dry state starting from chitosan complexes is discussed, using the preparation of copper (II) oxide as an example. Copper (II) oxide is widely used as catalyst in redox reactions and photochemical splitting of water. It also finds application in heat transfer fluids, semiconductors, gas sensors, batteries and magnetic storage media. It is expected that these properties may be enhanced in nano-sized particles of copper oxide and may lead to novel applications. Chitosan is an eco-friendly, biodegradable organic biopolymer obtained from the waste shells of prawns and crabs from sea food processing industries. Characterization of the synthesized material using scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopic (EDS) analyses are also described. The method is amenable to low-cost production of metal, metal oxide and other binary metal compounds on a large scale. The product is pure and does not contain any capping or stabilizers.
