酸性水溶液中でのカーボンナノチューブの酸素還元反応触媒活性

The performance of polymer electrolyte fuel cells (PEFCs) depends on the oxygen reduction reaction (ORR) at the cathode. Although platinum-supported carbon black has been used as the ORR catalyst in PEFCs, the use of platinum makes the cells expensive. Recently, platinum-free catalysts have been developed as cheap and long-life alternatives for excellent ORR catalytic activity. This review focusses on the acidic ORR catalytic activity of modified carbon nanotubes (CNTs) such as nitrogen-doped CNTs and defect-induced CNTs.
