Descrição: The immersed effects of Ta and Zr compounds (Ta–CNO and Zr–CNO) on the activity of oxygen reduction reaction (ORR) have been investigated in the sulfuric acid. The concentration of Zr on Zr–CNO was higher than that of Pt on Pt black. The concentration of Ta on Ta–CNO was almost the same as that of Pt on Pt black in sulfuric acid. The catalytic activity of Zr–CNO for the ORR decreased with time. In contrast, the catalytic activity of Ta–CNO for the ORR was maintained up to 1050 h in the sulfuric acid.
