One-step Redox-induced Confined Pt Nanoparticles for Reduction of Nitroaromatics

The noble metal nanoparticles sandwiched between the stable inorganic core and thin polymer shell could not only enhance their stability, but also cut short diffusion route of outside reactants through toward encapsulated nanoparticles, which has drawn great attention. However, weak compatibility among core, shell, makes preparation metal-confined hybrid catalysts complicated, limits popular application these metal-based catalysts. A facile method developed to fabricate core-shell Fe2O3@PEDOT/Pt nanocatalyst with tiny Pt highly dispersed in by one-step simultaneous redox deposition strategy. confinement effect strong coordination ability sulfur-enriched prevents migration agglomeration during catalytic process improves stability catalyst. catalyst shows outstanding activity relatively good towards reduction nitroaromatic compounds. simple solves problem poor confined material some extent. Furthermore, our strategy be extended Fe2O3@Polymer@Pt materials structure.
