摘要
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.
