“…However, the peaks at 1604 and 2925 cm −1 in the spectrum of pure PANI-rGO are shifted to 1587 and 2921 cm −1 , respectively, in the spectrum of the Pd-PANI-rGO composite. These band shifts to lower wavenumbers may have been caused by the relatively higher protonated state [37].…”

A composite consisting of polyaniline (PANI) and reduced graphene oxide (rGO) was synthesized by in situ polymerization of the monomer aniline in the presence of rGO under acidic conditions. The PANI-rGO composite substrate was doped with Pd nanoparticles via chemical reduction. The resulting Pd-PANI-rGO nanocomposite was characterized by transmission electron microscopy, scanning electron microscopy, X-ray diffraction, and Fourier-transform infrared spectroscopy before it was utilized to fabricate a hydrogen sensor. Compared with the sensor based on PANI-rGO or PANI, the Pd-PANI-rGO sensor was highly sensitive and selective to hydrogen gas, with fast response time in air at room temperature. The significantly enhanced sensitivity resulted from the faster spill-over effect, dissociation of hydrogen molecules on Pd, and the high surface area of the PANI-GO composite. Based on its improved sensing properties, ease of fabrication, and stable operation, the Pd-PANI-rGO nanocomposite shows promise for high-performance hydrogen-sensing applications.

“…There has been much research work on incorporating Pd into PANI to improve H 2 sensitivity. 17,[26][27][28][29][30] Nevertheless, the overall sensing performance of the Pd/PANI composites remains inferior compared with that of Pd and Pd-alloys. 1,2,16 It is generally considered that protonation at the nitrogen atoms of the PANI structure is retarded by anchoring Pd at the same sites, resulting in decreased conductivity of the PANI.…”

“…17 Because of the effective Pd-anchoring on the P(ANI-co-ASA):PSS nanostructure, the charge transport properties of P(ANI-co-ASA):PSS were not deteriorated by the complex formed from Pd NP ions and nitrogen atoms of the comonomers. [25][26][27][28][29] Accordingly, the P(ANI-co-ASA):PSS could provide enhanced interactions with H 2 gas molecules compared with the pristine P(ANI-co-ASA):PSS, while the loss of conductivity caused by the Pd-anchoring was not signicant. Furthermore, nanopores were successfully generated on the P(ANI-co-ASA):PSS surfaces using water-soluble porogen agents.…”

“…Therefore technology of the composite preparation acquires today a growing interest. Along with chemical procedures [1,2], electrochemical methods to synthesize palladium-filled composites are widely used and divided into two basic approaches. The first way consists in palladium reduction directly in the polymerization solution [3].…”

Polyaniline-palladium composite might be proposed for the electrode material in the oxidation of aliphatic alcohols (methanol, ethanol, ethylene glycol). Prepared mixture of aniline-palladium in sulfuric acid medium (0<рН<1) is investigated by SEM, PXD and FTIR. Obtained results confirm existence of three separate regions: polydisperse palladium powder with agglomerations size of ~0.5 micron in width and ~3-7 microns in length; single palladium particles (~0.5×0.2 micron) coated mainly by polyaniline form -emeraldine; aniline balls (diameter of ~2-5 microns) with ~0.2 atomic percent of Pd in their bulk and converted at the surface to emeraldine base and emeraldine salt.
