Highly dispersed Pt nanoparticles immobilized on 1,4-benzenediamine-modified …

Abstract. We demonstrate the use of molecular monolayers to enhance the nucleation of electrocatalytically active platinum (Pt) nanoparticles onto multi-walled carbon nanotubes (MWCNTs). The MWCNT is embedded within the 1,4-benzenediamine shell (NH2–MWCNT) with large amounts of amino groups outside on the nanotube surfaces. Subsequent deposition of platinum nanoparticles led to high densi…
