| Abstract: | In this study, we report the hydrogen sensing properties of the Pt dispersed graphitic carbon nitride (g-C3N4) nanocomposite at room temperature and inert atmosphere. The nanocomposite was synthesized by a wet-chemical approach, where melamine and chloroplatinic acid hexahydrate were used as precursors. The fabrication of the sensor was done by jet nebulizer-based spray pyrolysis setup. Various characterizations were performed for the analysis of the synthesized nanocomposite. Electrical resistance in the presence and absence of the analyte gas was drastically different. The results at different concentrations and film thickness show Pt/g-C3N4 to possess good sensitivity towards the hydrogen gas, suggesting that it could be used for reliable hydrogen gas sensing. |
