• Ta-C-N electrocatalysts were prepared by reactive R.F. sputtering with heat treatment in the temperature range from 70 to 800°C. The Ta-C-N was found to have high electrochemical stability in 0.1 mol dm−3 H2SO4. The catalytic activity for the oxygen reduction reaction of the sputtered Ta-C-N increased with the increasing heat treatment temperature. In particular, the current of the ORR on the Ta-C-N with the heat treatment temperature of 800°C was observed at about 0.73 V vs. RHE. It was found that the crystallinity of the Ta-C-N would affect the catalytic activity for the ORR.
