Improving the HER Activity and Stability of Pt Nanoparticles by Titanium Oxynitride Support.

ABSTRACT: Water electrolysis powered by renewables is regarded as the feasible route for the production of hydrogen, obtained at the cathode side through electrochemical hydrogen evolution reaction (HER). Herein, we present a rational strategy to improve the overall HER catalytic performance of Pt, which is known as the best monometallic catalyst for this reaction, by supporting it on a conductive titanium oxynitride (TiON _x ) dispersed over reduced graphene oxide nanoribbons. Characterization of the Pt/TiON _x composite revealed the presence of small Pt particles with diameters between 2 and 3 nm, which are well dispersed over the TiON _x support. The Pt/TiON _x nanocomposite exhibited improved HER activity and stability with resp
