A General Approach to the Size-and Shape-Controlled Synthesis of Platinum Nanoparticles and Their Catalytic Reduction of Oxygen

摘要

The synthesis of platinum nanoparticles(Pt NPs)with controlled sizes and shapes is an attractive goal in developing highly active platinum catalysts for the synthesis of fine chemicals.Well-dispersed Pt NPs are also an important catalyst for fuel-cell reactions:in commonly studied polymer electrolyte membrane fuel cells(PEMFCs),they catalyze hydrogen oxidation at the anode and oxygen reduction at the cathode.
