Abstract
We report the large scale preparation of nanostructured polyaniline‐Pd nanoparticles composites (designated as PANI(NS)‐PdNPs) through a “seed” induced bulk polymerization. Initially, a small quantity of PANI(NS)‐PdNPs was formed inside the cavities of MCM‐41 and used as the “seed” for the bulk preparation of PANI(NS)‐PdNPs composite. For a comparative purpose a PANI‐PdNPs composite was also prepared in the absence of the seed. FESEM image of PANI(NS)‐PdNPs composite (bulk) shows nanofibrillar morphology. Further, transmission electron microscopy reveals the presence of spherical Pd nanoparticles. PANI(NS)‐PdNPs composite (bulk) showed a good catalytic activity towards reduction of 4‐nitrophenol.
