Summary: Transition metal Co-based materials, such as layered double hydroxides (LDHs), can undergo electrochemical reconstruction under oxygen evolution reaction (OER) conditions to form highly active Co4 species. However, controlling the formation of these species remains challenging. In this study, the leaching of Al3 after OER activation successfully induces the formation of high-valent Co4 species on CoFeAl LDH, leading to an electrocatalyst with excellent OER performance. This work provides insights into surface reconstruction and activity promotion using leachable cations to induce high-valent metal active sites in other electrocatalysts.

Summary: High-entropy layered double hydroxides (HE-LDHs) are promising electrocatalysts for OER due to their high-entropy effect and the cocktail effect. However, their catalytic activity and stability are still unsatisfactory. In this study, we designed FeCoNiCuZn LDHs with rich cation vacancies, which exhibited low overpotentials and excellent stability. DFT calculations confirmed that the cation vacancies enhanced the intrinsic activity of HE-LDHs by optimizing the adsorption energy of OER intermediates.

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: 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.

Summary: The electro-reductive coupling of nitro and carbonyl compounds provides a convenient, environmentally friendly and energy benign method for the synthesis of valuable nitrones or imines, but achieving high selectivity remains challenging. In this study, the surface roughness of Cu electrodes is introduced as a determinant to control the switch from nitrones to imines by the controllable reduction of nitroarenes on tailored Cu-I/Cu-0 interfaces. The selectivity of nitrones and imines can be modulated by adjusting the roughness of the Cu electrode, with higher roughness leading to decreased nitrones and increased imines. This surface roughness-dependent selectivity is demonstrated in a wide range of substrates, highlighting the potential of surface engineering for electrochemical synthesis.

Summary: In this research, a three-step preactivation process was proposed to reconstruct commercial nickel foam (CNF) as an efficient electrocatalyst for the oxygen evolution reaction (OER). The activated CNF showed excellent OER performance in alkaline media and could tolerate long-term tests under a large current density. The calcination step led to a reconstructive surface morphology, the high-voltage treatment changed the valence of surface Ni species, and the immersion process introduced Fe heteroatoms into the CNF surface, all contributing to the improved catalytic performance.
