The catalytic
degradation of azo dyes, a potentially harmful environmental
contaminant, using FePt PS@NPs spheres demonstrates the
utility of these materials in catalytic reactions. These studies
also provided further insight into the colloidal stability of the
decorated PS spheres. The FePt NPs were chosen for this
study due to their monodisperse size and shape, which was
necessary in order to appropriately assess changes in the
loading and distribution of NPs within the coatings.
