Abstract

Titanium nitride nanoparticles act as a catalyst support material for proton exchange membrane fuel cells showing higher catalytic performance than conventional platinized carbon electrocatalysts.

Supplementary files

The proof for the presence of surface oxide layer on TiN is presented using an XPS image and the X-ray diffraction data of lattice parameters. A TEM image of Pt/TiN is included to show that most of the Pt particles are supported on the TiN supports. An X-ray map of Pt/TiN is included for the elements Ti, N and Pt to indicate the uniformity of the Pt distribution on TiN. A TEM-based EDS image is presented to show the elements involved in Pt/TiN PDF (1230K)
