“…The existence of these interconvertible oxidation states of polyaniline facilitates a spontaneous reduction of Pd(II) ions in acidic solution to their elemental form . This results in a uniform seeding of the surface with palladium metal, which effectively catalyzes the copper plating reaction ,− leading to a continuous nucleation of the metal. Metal deposition on polyaniline functionalized coaxial fibers without pretreatment with Pd(II) ions resulted in formation of noncontinuous metal layer on the fiber surface as shown in SEM image Figure .…”

Submicrometer tubes have been fabricated by a polymer-based template approach using electroless deposition. The copper was deposited on polystyrene fibers functionalized with an interfacial electrically conducting polyaniline thin film layer. Thermal degradation of the functionalized fiber templates resulted in copper tubes of diameter 1600 ± 50 nm with wall thicknesses ranging between 100 and 200 nm. The morphology and elemental analysis of copper coaxial fibers was analyzed using SEM and EDS. Electrical properties were analyzed using FTIR and PXRD was used to study crystal structure of copper nanotubes.

Composite palladium membranes have extensively been studied in laboratories and, more recently, in small pilot industrial applications for the high temperature separation of hydrogen from reactant mixtures such as water‐gas shift (WGS) reaction or methane steam reforming (MSR). Composite Pd membrane fabrication methods have matured over the last decades, and the deposition of very thin films (1–5 µm) of Pd over porous ceramics or modified porous metal supports is quite common. The H 2 permeances and the selectivities achieved at 400–500 °C were in the order of 50–100 Nm 3 /m/h/bar 0.5 and greater than 1000, respectively. This chapter describes in detail composite Pd‐based membrane preparation methods, which consist of the grading of the support and the deposition of the dense metal layer, their performances, and their applications in catalytic membrane reactors (CMRs) at high temperatures (400–550 °C).
