Catalytic Activity of Ni@Pd Supported on Yolk-Shell Fe3O4@Polyaniline Composites for Nitro Reduction

The preparation of Ni@Pd core-shell nanoparticles immobilized on the yolk-shell Fe3O4@polyaniline (PANI) composites is reported. The approach uses polyaniline conductive polymer as a templates for the synthesis of Ni@Pd core-shell nanoparticles which promotes the catalytic performance. The catalytic activity of the synthesized yolk-shell Fe3O4@PANI/Ni@Pd composite was investigated in reduction of o-nitroaniline (o-NA) to benzenediamine by NaBH4 which exhibited conversion of 99% in 3 min with a very low content of the catalyst. XPS, EDS, and SEM were employed to characterize the synthesized magnetically recoverable nanocatalyst
