We report the formation of palladium nanoparticle (PdNP)âlithocholic acid (LCA) composite nanofibers by the self-assembly of Pd2+-coordinated LCA molecules and an ex situ reduction. The ex situ reduction by sodium borohydride or ascorbic acid produces the composite nanofibers with PdNPs grown on the surface of LCA nanofibers. The catalytic activity of the PdNPâLCA composite nanofibers in the decolourization of 4-phenyl azo benzoic acid is investigated. We find that the composite nanofibers can be recycled without significantly losing their catalytic activities.
