Catalyst, process for preparing the same, and uses of the catalyst |
摘要 |
The present invention provides a catalyst which is not corroded in an acidic electrolyte or at a high potential, is excellent in durability and has high oxygen reduction ability. The catalyst of the present invention is characterized by including a niobium oxycarbonitride. The catalyst of the invention is also characterized by including a niobium oxycarbonitride represented by the composition formula NbCxNyOz, wherein x, y and z represent a ratio of the numbers of atoms and are numbers satisfying the conditions of 0.01≦x≦2, 0.01≦y≦2, 0.01≦z≦3 and x+y+z≦5. |
