Local electrocatalytic activity of PtRu supported on nitrogen doped carbon nanotubes towards methanol oxidation by scanning electrochemical microscopy

Abstract

Nitrogen-doped carbon nanotubes (NCNTs) were synthesized by treating HNO3-oxidized carbon nanotubes (CNTs) in NH3 flow at different temperatures. PtRu nanoparticles were decorated over NCNTs. The PtRu catalysts were prepared by...
