Cover Story (view full-size image): Sustainable star-like octahedron or decahedron Pd/Pt nanoparticles were synthesized by a novel and selective green approach using a bioconjugate of chitosan and polyhydroxybutyrate (Cs–PHB). The bimetallic Pd/Pt nanoparticle alloys synthesized with various Pd/Pt molar ratios were successfully applied in the catalytic reduction of 4-nitrophenol to 4-aminophenol by borohydride. The calculated κc values (estimated ratio between pseudo-first-order kinetic rate constants (s−1) values and the catalyst concentrations (g/L)) revealed that the decahedron nanoparticles exhibited excellent catalytic activity compared to other bimetallic nanoparticles reported in the literature.
