“…Working with Pd NPs-decorated nanoporous poly(aniline-co-aniline-2-sulfonic acid):poly(4-styrenesulfonic acid) (P(ANI-co-ASA):PSS), Cho et al [77] reported the fabrication of a hydrogen sensor with a limit of detection of 5 ppm H 2 in air at room temperature and presenting 90 s and 40 s for respectively response and recovery times. While the characteristic detection times still must be improved, the limit of detection obtained in this work is quite low and therefore very promising for leak detection applications.…”

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.

“…Conductive polymer nanomaterials can be used for the organic component as a template for nanocomposites and a charge transfer pathway due to the conjugated polymer backbone structure in the sensor transducer [ 24 , 25 , 26 , 27 ]. Among them, polypyrrole is one of the most well-known conducting polymers that comprises five-membered heterocyclic rings and exhibits beneficial characteristics in a hydrogen sensing system [ 28 , 29 , 30 , 31 ].…”

Despite being highly flammable at lower concentrations and causing suffocation at higher concentrations, hydrogen gas continues to play an important role in various industrial processes. Therefore, an appropriate monitoring system is crucial for processes that use hydrogen. In this study, we found a nanocomposite comprising of ruthenium nanoclusters decorated on carboxyl polypyrrole nanoparticles (Ru_CPPy) to be successful in detecting hydrogen gas through a simple sonochemistry method. We found that the morphology and density control of the ruthenium component increased the active surface area to the target analyte (hydrogen molecule). Carboxyl polypyrrole (CPPy) in the nanocomposite was protonated to increase the charge transfer rate during gas detection. This material-based sensor electrode was highly sensitive (down to 0.5 ppm) toward hydrogen gas and had a fast response and recovery time under ambient conditions. The sensing ability of the electrode was maintained up to 15 days without structure deformations.

A dodecylbenzene sulfonic acid (DBSA) doped-polyaniline (PANI) coated conductive viscose fiber (VCF) was prepared by chemical oxidation polymerization in an ethanol/water solution. Fourier transform infrared spectra (FTIR) and XPS proved that an interaction between PANI and VCF formed in the PANI/VCF composites. The mild treatment did not result in the oxidation and degradation of VCF detected by thermal gravimetric analysis (TGA) and mechanical testing. Moreover, the influence of the reaction conditions including reaction time, aniline monomer (ANI) concentration, ammonium persulfate (APS) concentration and DBSA concentration on the morphology and the conductivity of the PANI/VCF composites were investigated in detail. The orthogonal experiments were designed to determine the optimal reaction conditions as follows: ethanol/water ratio (30/70), reaction time (18 h), ANI concentration (0.1 mol L À1 ), APS concentration (0.125 mol L À1 ) and DBSA concentration (0.1 mol L À1 ).When the PANI/VCF composite was washed 40 times in water, the conductivity still remained at 2.5 Â 10 À2 S cm À1 , and this value was stable for more washing.
