Graphene-Based Metal Oxide Nano Composites For Gas Sensing Applications

Abstract

Recently, graphene-based materials have engaged the attentiveness of all researchers doing
research related to materials science, particularly related to gas sensing application.
Graphene nanocomposites or nanohybrids are the modern inclusion to the marvel
applications of graphene-based materials. One of the occupying utilisation of the graphene-
based nanocomposites is chemical detection which is beneficial for observing the explosive
nature, harmfulness and inflammability of gases. Diversified metal oxides like tin oxide,
ferric oxide, zinc oxide and indium oxide as soon as combined with graphene-based
materials to form nanocomposites own enormous potentiality for detecting a minute amount
of harmful gas. In this article, the various synthesising methods, preparation of composites,
fabrication and gas sensing utilisation of graphene-based nanocomposites are depicted in
detail.
