Enhanced ammonia detection using rGO-wrapped Zn3V2O8 nanostructures

This study presents the synthesis and characterization of reduced graphene oxide (rGO)-wrapped Zn3V2O8 nanostructures, highlighting their enhanced ammonia sensing capabilities. Utilizing advanced techniques such as XRD, TEM, HRTEM, XPS, and Raman spectroscopy, the microstructural, compositional, and crystalline properties of the rGO/ Zn3V2O8 composites were thoroughly analyzed. The integration of rGO significantly improves the electrical conductivity, surface area, and chemical reactivity of the Zn3V2O8, resulting in superior sensing performance. Notably, the rGO/Zn3V2O8:2 composite exhibits rapid response and recovery times when detecting ammonia at room temperature, demonstrating its potential as an effective material for advanced gas sensing applications. These findings contribute to the ongoing development of high-performance ammonia sensors, offering a promising approach for real-time environmental monitoring and industrial applications.
