| Abstract: | Replacing the rare and precious platinum (Pt) electrocatalysts with earth‐abundant materials for promoting the oxygen reduction reaction (ORR) at the cathode of fuel cells is of great interest in developing high‐performance sustainable energy devices. However, the challenging issues associated with non‐Pt materials are still their low intrinsic catalytic activity, limited active sites, and the poor mass transport properties. Recent advances in material sciences and nanotechnology enable rational design of new earth‐abundant materials with optimized composition and fine nanostructure, providing new opportunities for enhancing ORR performance at the molecular level. This Review highlights recent breakthroughs in engineering nanocatalysts based on the earth‐abundant materials for boosting ORR. |
