Highly Sensitive NH(3) Wireless Sensor Based on Ag-RGO Composite Operated at Room-temperature

The detection of ammonia (NH(3)) in low concentrations is very important in the chemical industry and for human health. In this paper, we present reduced graphene oxide (RGO) decorated with silver nanoparticles (AgNPs) as a sensing material for NH(3). A simple, environmentally friendly, and cost-eff...

description The detection of ammonia (NH(3)) in low concentrations is very important in the chemical industry and for human health. In this paper, we present reduced graphene oxide (RGO) decorated with silver nanoparticles (AgNPs) as a sensing material for NH(3). A simple, environmentally friendly, and cost-efficient green approach for the preparation of the sensing material is proposed. X-ray diffraction (XRD), Raman spectroscopy, and field emission scanning electron microscopy (FE-SEM) were used to analyze the crystalline structure, material composition, and surface appearance characteristics of the sensing material. By combining the material with a commercial near-field communication (NFC) tag, a wireless gas sensor was built. The enhanced NH(3)-sensing performance is mainly due to the synergistic effect between Ag and RGO. More specifically, AgNPs enhanced the adsorption capacity of RGO for NH(3) electrons. The excellent performance of the sensor shows that it has potential for applications in food safety, environment, and human health monitoring.
