Interface engineering of CeO nanoparticle/BiWO nanosheet nanohybrids with oxygen vacancies for oxygen evolution reactions under alkaline conditions.

Because of the interactive combination synergy effect, hetero interface engineering is used way for advancing electrocatalytic activity and durability. In this study, we demonstrate that a CeO/BiWO heterostructure is synthesized by a hydrothermal method. Electrochemical measurement results indicate that CeO/BiWO displays not only more OER catalytic active sites with an overpotential of 390 mV and a Tafel slope of 117 mV dec but also durability for 10 h (97.

Hollow CoFe-based hybrid composites derived from unique S-modulated coordinated transition bimetal complexes for efficient oxygen evolution from water splitting under alkaline conditions.

The oxygen evolution reaction (OER) is an important reaction in water splitting. However, the high cost and slow-rate catalysts hinder commercial applications. Although an important process for manufacturing of hollow structures, it is difficult to construct complicated hollow structures with an excellent and regulable shape for multi-component materials.
