Synthesis, Self‐Assembly, and Electrocatalysis of Polyallylamine‐Functionalized Platinum Nanocubes

The title composite was prepared and self-assembled on carbon nanotubes (CNTs). Even after cleaning with UV/Ozone and electrochemical methods, the residual polyallylamine strongly influences the electronic structure of Pt. The resultant Pt-NC/CNT nanohybrid shows superior electrochemical activity and stability towards the oxygen reduction reaction in H2SO4 solutions compared with commercial Pt/C catalyst.
