“…Despite the good performances recorded for electrical hydrogen detection systems working by use of Pd NPs, some issues still need to be faced with this type of sensor [15,89,90]. Safety and sensor longevity issues due to the use of electrical contact in harsh environment are major challenges that these electrical sensors have to overcome [89].…”

“…It must be noted that literature mostly provides results from Pd films-based compared to Pd NPs-based optical H 2 sensors. Due to the increased surface to volume ratio, the use of Pd NPs may provide improved performances resulting from higher effective surface available for interaction of Pd with the hydrogen gas molecules [15]. The use of nanoparticles has several advantages, such as the possibility to engineer the sensor response time owing to materials design and also by tailoring the particles dimensions to reduce gas diffusion times [11].…”

“…Among them, the use of palladium and platinum materials has been and is still deeply investigated by several research teams due to their high sensitivity to hydrogen; especially Pd because of its very high hydrogen absorption capacity. Moreover, the use of Pd nanoparticles (NPs) may provide improved performances compared to the use of bulk Pd due to the increased surface to volume ratio that induces a higher effective surface available for interaction of Pd with the hydrogen gas molecules [15]. Thanks to the use of nanoparticles, it may be possible to engineer the sensor response time through materials design.…”

Along with the development of hydrogen as a sustainable energy carrier, it is imperative to develop very rapid and sensitive hydrogen leaks sensors due to the highly explosive and flammable character of this gas. For this purpose, palladium-based materials are being widely investigated by research teams because of the high affinity between this metal and hydrogen. Furthermore, nanostructured palladium may provide improved sensing performances compared to the use of bulk palladium. This arises from a higher effective surface available for interaction of palladium with the hydrogen gas molecules. Several works taking advantage of palladium nanostructures properties for hydrogen sensing applications have been published. This paper reviews the recent advances reported in the literature in this scope. The electrical and optical detection techniques, most common ones, are investigated and less common techniques such as gasochromic and surface wave acoustic sensors are also addressed. Here, the sensor performances are mostly evaluated by considering their response time and limit of detection.

“…Developed NO 2 sensors using 1 mol% Pd-loaded In 2 O 3 hierarchical microstructures showed exceptional NO 2 detection at a further lower operating temperature of 110 °C, though other prevalent chemicals like H 2, CO, CH 4 , and ethanol were present [ 43 ]. The performance of palladium nanoparticles compared to the bulk Pd is more because of the increased surface to volume ratio that further leads to a higher effective surface for the interaction of palladium [ 44 ]. Thus, addition of palladium to SnO 2 nanoparticles will tend to increase the sensitivity toward carbon monoxide and the gas-sensing property.…”

The exhaust gases from various sources cause air pollution, which is a leading contributor to the global disease burden. Hence, it has become vital to monitor and control the increasing pollutants coming out of the various sources into the environment. This paper has designed and developed a sensor material to determine the amount of carbon monoxide (CO), which is one of the major primary air pollutants produced by human activity. Nanoparticle-based sensors have several benefits in sensitivity and specificity over sensors made from traditional materials. In this study, tin oxide (SnO2), which has greater sensitivity to the target gas, is selected as the sensing material which selectively senses only CO. Tin oxide nanoparticles have been synthesized from stannous chloride dihydrate chemical compound by chemical precipitation method. Palladium, at the concentration of 0.1%, 0.2%, and 0.3% by weight, was added to tin oxide and the results were compared. Synthesized samples were characterized by X-ray diffraction (XRD) and field emission scanning electron microscope (FESEM) techniques. XRD revealed the tetragonal structure of the SnO2 nanoparticles and FESEM analysis showed the size of the nanoparticles to be about 7–20 nm. Further, the real-time sensor testing was performed and the results proved that the tin oxide sensor, doped with 0.2% palladium, senses the CO gas more efficiently with greater sensitivity.
