A semiconductor rich in oxygen vacancies is introduced by Zhengyu Bai, Zhongwei Chen, and co‐workers in article number 1806761 to design an efficient and durable non‐precious‐metal bifunctional oxygen electrocatalyst in alkaline conditions. The oxygen vacancies promote the electrical conductivity of the oxide support, and at the same time offer a strong metal–support interaction, which gives a small metal size, high catalytic activity, and stability. This is demonstrated by synthesizing ultrafine Co‐metal‐decorated three‐dimensionally ordered macroporous titanium oxynitride.
