Sputter-Deposited Binder-Free Nanopyramidal Cr/γ-Mo₂N TFEs for High-Performance Supercapacitors.

ABSTRACT: Due to their outstanding power density, long cycle life and low cost, supercapacitors have gained much interest. As for supercapacitor electrodes, molybdenum nitrides show promising potential. Molybdenum nitrides, however, are mainly prepared as nanopowders via a chemical route and require binders for the manufacture of electrodes. Such electrodes can impair the performance of supercapacitors. Herein, binder-free chromium (Cr)-doped molybdenum nitride (Mo₂N) TFEs having different Cr concentrations are prepared via a reactive co-sputtering technique. The Cr-doped Mo₂N films prepared have a cubic phase structure of γ-Mo₂N with a minor shift in the (111) plane. While un-doped Mo₂N films exhibit a spherical morphology, Cr-doped Mo₂N films
