Graphene-Oxide Nano Composites for Chemical Sensor Applications

Of late, graphene has occupied the attention of almost all researchers working globally in the area of materials science. Graphene nanocomposites are the latest additions to the wonder applications of graphene. One of the promising applications of the graphene-oxide nanocomposites is chemical sensing which is useful for monitoring the toxicity, inflammability, and explosive nature of chemicals. Well known binary oxides like ZnO, TiO2, SnO2, WO3, and CuO when combined with graphene in the form of nanocomposites have excellent potential for detecting trace amounts of hazardous gases and chemicals. In this article the preparations, characterizations, and the chemical sensor applications of graphene-oxide nanocomposites are presented in detail.
