Titanium nitride– carbon nanotube core–shell composites as effective electrocatalyst supports for low temperature fuel cells

Titanium nitride–carbon nanotube (TiN–CNT) core–shell nanocomposites were developed by a simplistic two step fabrication procedure and characterized by transmission electron microscopy, X-ray diffraction and thermogravimetric analysis. These materials were utilized as platinum nanoparticle electrocatalyst supports (Pt/TiN–CNT) for the oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR), two important low temperature fuel cell …
