Abstract
Graphene is a one-atom-thick two-dimensional structure of carbon arranged in a hexagonal structure. Due to its unique mechanical and electronic properties, graphene has become very promising material. It has good sensing characteristics like large surface area, potentially available
binding site, etc. In this report, the hybrid system of NiCo2S4 synthesized by two-step hydrothermal method and graphene transferred to IDE (Interdigit electrode) was prepared for gas sensing applications. Chemical Vapor Deposition (CVD) method was used to grow graphene
on copper foil and transferred to different substrates by wet etching of Cu foil. After the synthesis and transfer of graphene to the substrate, Raman spectroscopy was used to has effectively improve ion and charge transportation. Scanning electron microscopy (SEM) was used to check the morphology
of material. X-ray diffraction (XRD) is used to check the properties of the material. This proposed sensor has a high response, good selectivity, and stability to 100 ppm ammonia at room temperature. Moreover, the sensor material which is synthesized with graphene has promising applications
in future gas sensing devices.
