Abstract
The presence of certain volatile organic compounds is used for the detection of fungi in the indoor environments. The synthesis of SnO2/Pd nanoparticles (NPs) was performed via the reduction of Pd2+ in the presence of l-glycine. The XRD and EDX results confirmed the presence of palladium on the surface of SnO2 NPs. The sensing properties of SnO2/Pd and SnO2 NPs towards the detection of 1-octen-3-ol were analyzed by a static process. The SnO2/Pd and SnO2 NPs fabricated sensors gave a response of 46.7% and 24.2%, respectively, for 700 ppm target gas at 250 °C. The estimated limit of detection and limit of quantification of the fabricated SnO2/Pd sensor at 250 °C in the linear segments are 20.94 ppm and 69.79 ppm, respectively. These results demonstrated that the synthesis of SnO2/Pd NPs in the presence of l-glycine as a reducing agent has potential applications in the detection of fungal biodeterioration in infected materials at the early stages of infection.
