Electrostatic self-assembly of platinum nanochains on carbon nanotubes: A highly active electrocatalyst for the oxygen reduction reaction

A facile approach is used to synthesize a multiwalled carbon nanotubes (MWCNTs) supported platinum nanochains (Pt-NCs) catalyst through the electrostatic self-assembly between phosphonate functionalized Pt-NCs and polyallylamine (PAH) functionalized MWCNTs. It is observed that Pt-NCs are highly dispersed and effectively anchored on the surface of PAH functionalized MWCNTs.
