In article number 1700005 , Fei Teng, Tierui Zhang, and co‐workers report a noble‐metal‐free bifunctional electrode consisting of ultrathin manganese dioxide (δ‐MnO 2 ) nanosheet arrays on a nickel foam, exhibiting high performance for HER and OER. The remarkable overall water splitting activity is mainly attributed to the numerous active sites and excellent electrical conductivity of δ‐MnO 2 nanosheets, containing abundant oxygen vacancies and unsaturated Mn 3+ sites due to the near monolayer thickness.
