| Abstract: | Metal oxide hollow structures with large surface area, low density, and high loading capacity have received great attention for energy‐related applications. Acting as oxygen‐related catalysts, hollow‐structured transition metal oxides offer low overpotential, fast reaction rate, and excellent stability. Herein, recent progress in the oxygen‐related catalysis (e.g., oxygen evolution reaction (OER), oxygen reduction reaction (ORR), and metal–air batteries) of hollow‐structured transition metal oxides is discussed. Through a comprehensive outline of hollow‐structured spinels, perovskites, rutiles, etc., a rational design strategy is provided for an enhanced oxygen‐related catalysis performance from the viewpoint of crystal structures. Urgent challenges and further research directions are presented for hollow‐structured transition metal oxides toward excellent oxygen‐related catalysis. |
