It is of great challenge to design transition multimetallic carbonate hydroxides with delicate hollow features and defects for efficient electrolytic oxygen evolution reaction (OER). Here, a sequential self‐templating method to synthesize CoNiFe trimetallic carbonate hydroxide hierarchical hollow microflowers (CN‐xFe HMs) with oxygen vacancies (VO) is reported. The synergistic merits of hollow structure,...
Ternary transition metal oxides (TMOs) are highly potential electrode materials for lithium ion batteries (LIBs) due to abundant defects and synergistic effects with various metal elements in a single structure. However, low electronic/ionic conductivity and severe volume change hamper their practical application for lithium storage. Herein, nanosheet‐assembled hollow single‐hole Ni–Co–Mn oxide (NHSNCM)...
Herein, Ni and Zn elements are doped simultaneously in MnCO3 and microspheric MnxNiyZnzCO3 is successfully obtained. Atomic mapping images reveal that the Ni and Zn elements have been successfully doped in MnCO3 and thus the prepared sample is not a mixture of MnCO3, NiCO3, and ZnCO3. It is the first time that the atomic mapping images of ternary transition metal carbonates have been demonstrated...
