abstract = "Oxygen reduction reaction (ORR) activity and electrochemical structural stability of Pt/Ta-carbide nanoparticles (Pt/TaCx NPs) were investigated. The Pt/TaCx NPs were fabricated via arc plasma deposition (APD) of Ta under CH4 partial pressure (0.05 Pa) onto a highly oriented pyrolytic graphite (HOPG) substrate, followed by electron-beam deposition of Pt in ultra-high vacuum (UHV;-10{"}' Pa). X-ray diffraction patterns of the APD-TaCx samples showed that the diffraction peak due to TaC (rock-salt structure), exhibiting tantalum carbide which can be synthesized through the APD of Ta in CH4 atmosphere. The ORR activity of pristine Pt/TaCx samples is higher than that of the Pt/Ta alloy NPs prepared in UHV. Furthermore, the accelerated durability test results showed that the carbonization of Ta improves the ORR durability. The results clearly reveal that early transition metal carbides, e.g., TaC, are effective as core materials of core-shell-type Pt-based ORR catalysts.",
