Synthesis and structural, microstructural and humidity sensing behavior of (x)rGo+(1-x)CoCr2O4 composite for humidity sensor applications

Immediate research is needed to determine why monolayer carbon atom (rGO) composites function so poorly as humidity sensors. Here, an attempt is made on (x)rGo+(1-x)CoCr2O4(x = 0,0.1,0.2 and 0.3) composite for humidity sensor. The method is straightforward, cheap, and basic, making it ideal for mass-producing (x)rGo+(1-x) CoCr2O4 composite. In this research, we investigate whether or not the (x)rGo+(1-x)CoCr2O4 composite can be used to improve the responsiveness of humidity sensors at ambient temperature. The use of X-ray diffraction allows for the investigation of crystallinity, phase, and structure (XRD). Crystallite size were estimated and found 9-11 nm. Morphology of the samples were seen ultrathin, wrinkled, paper-like, spherical type image. Samples were subjected to study the humidity sensing behavior. Within the range of 11%-97% RH, CCR-most rGO's impressive sensing response was 92%. The compound's stability was evaluated over the course of three months, and its response time was found to be between 32 and 36 s. To illustrate the mechanism of humidity sensing, we will use the stages of an adsorption process. For x = 0.3 concentration we observed high sensing response.

Automated summary

Immediate research is needed to investigate the poor performance of monolayer carbon atom (rGO) composites as humidity sensors. In this study, a (x)rGo+(1-x)CoCr2O4(x = 0,0.1,0.2 and 0.3) composite was tested as a humidity sensor. The method used was simple, cost-effective, and suitable for mass production. The research aimed to determine if the (x)rGo+(1-x)CoCr2O4 composite could enhance the responsiveness of humidity sensors at room temperature. X-ray diffraction (XRD) was used to analyze the crystallinity, phase, and structure of the composite. The results showed that the compound had a high sensing response at a concentration of x = 0.3.
