Polymer-stabilized palladium nanoparticles for catalytic membranes: ad hoc polymer fabrication.

Domènech B, Muñoz M, Muraviev DN, Macanás J - Nanoscale Res Lett (2011)

Bottom Line: This paper reports the intermatrix synthesis of Pd0 nanoparticles in sulfonated polyethersulfone with Cardo group membranes and their use as nanocomposite catalytic membrane reactors.The synthesized polymer and the corresponding nanocomposite were characterized by spectroscopic and microscopic techniques.The catalytic efficiency of catalytic membranes was evaluated by following the reduction of p-nitrophenol in the presence of NaBH4.

ABSTRACT
Metal nanoparticles are known as highly effective catalysts although their immobilization on solid supports is frequently required to prevent aggregation and to facilitate the catalyst application, recovery, and reuse. This paper reports the intermatrix synthesis of Pd0 nanoparticles in sulfonated polyethersulfone with Cardo group membranes and their use as nanocomposite catalytic membrane reactors. The synthesized polymer and the corresponding nanocomposite were characterized by spectroscopic and microscopic techniques. The catalytic efficiency of catalytic membranes was evaluated by following the reduction of p-nitrophenol in the presence of NaBH4.

Figure 3: TEM images and size distribution histograms of two Pd0-MNP samples prepared in the same way.

Mentions: Figure 3 shows typical TEM images of Pd0-NPs synthesized inside SPES-C matrix and their size distribution histograms. As it is seen, Pd forms almost spherical nanoparticles characterized by quite narrow size distribution with the most frequent diameters lying inside the 4- to 8-nm range. Particles are well separated from each other, which testifies to the high stabilizing efficiency of SPES-C matrix towards Pg-MNPs.
