Graphene-Based Metal Oxide Nano composites for Gas Sensing Applications

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.
