Overall Performance

Nanoporous composition-tunable PtPd catalysts, combining with a high density of twin boundaries and atomic-scale Pt–Pd interfaces, can be synthesized by a simple thermal-decomposition strategy. The most optimized PtPd represents the superior overall performance high catalytic activity and stability in the electrochemical oxidation of methanol.

Pet Substrate

We report a facile synthesis of PtNi nanosheets on the flexible ITO/PET substrate by electrochemical deposition method. The morphology and composition of the PtNi nanosheets were characterized and it was revealed that the PtNi nanosheets were polycrystalline with a thickness of about 4 nm. The average Ni content in the nanosheets was about 10 at%. The results of the electrochemical measurements showed that the PtNi nanosheets have excellent catalytic activity and stability toward the electro-oxidation of methanol in alkaline medium, which making it more attractive for fuel cell applications.
