Summary: Efficient and economic bifunctional electrocatalyst for water splitting to produce hydrogen is urgently required. Layered double hydroxides (LDHs) are effective for oxygen evolution reaction (OER) but show challenging hydrogen evolution reaction (HER) activity. A hydrothermal-treatment strategy enhances the HER and OER performance of NiCo-LDH by creating metal vacancies and forming Ni/Co(OH)2 phase, tuning electronic structure, and improving electrical conductivity. The resulting NiCo-LDH-OH catalyst exhibits significantly reduced overpotentials for both HER and OER, and demonstrates superior activity for overall water splitting with no decay after 20 hours. This work paves a new path for efficient LDHs-based HER/OER bifunctional catalysts.

Summary: The oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are crucial half-cell reactions in energy storage and conversion devices, which require efficient and stable electrocatalysts due to their slow kinetics and large overpotential. Transition-metal-based LDHs and their derivatives have shown promising catalytic performance, and regulating the structure and coordination environment of active sites can greatly influence electrocatalytic behavior. Understanding the relationships between structural performance and chemical composition of LDHs-based electrocatalysts can lead to further rational design and optimization of high-performance materials.

Summary: Oxygen vacancies (Ov) engineering has been shown to greatly enhance electrocatalytic kinetics for oxygen evolution reaction (OER) by improving electronic transport. However, the mechanism behind this enhancement is not well understood. In this study, we investigate the role of superficial Ov in enhancing the catalytic potential of NiFe layered double hydroxides for OER. We find that superficial Ov engineering significantly reduces the charge transport resistances and modulates the utilization rate of active sites for OER catalysis.
