The electrochemical N2 reduction reaction (NRR) is a green and energy-saving sustainable technology for NH3 production. However, high activity selectivity can hardly be achieved in the same catalyst, which severely restricts development of NRR. In2Se3 with partially occupied p-orbitals suppress H2 evolution (HER), shows excellent presence VIn simultaneously provide active sites confine Re clusters through strong charge transfer. Additionally, well-isolated stabilized on by confinement effect result Re-VIn maximum availability. By combining as dual spontaneous adsorption activation, NRR performance enhanced significantly. As result, Re-In2Se3-VIn/CC catalyst delivers yield rate (26.63 μg h–1 cm–2) FEs (30.8%) at −0.5 V vs RHE.

Abstract The exceptional electronic properties and potential applications of black phosphorus (BP) have garnered significant interest in the fields electrochemical catalysis energy storage. However, its poor environmental stability severely hampers practical use. In this study, an innovative strategy is proposed to protect fresh phosphorene (BP ene ) against oxidation by adsorbing or weakly bonding aluminum ions (Al 3+ onto surface, while facilitating their self‐removal under operating conditions. By leveraging Al ‐protected (Al‐BP as a catalyst for electrocatalytic reduction nitrogen ammonia (NH 3 ), effectiveness removable demonstrated. Quantitative analysis reveals that Al‐BP maintains structural compositional over 7 days ambient conditions, can be readily eliminated through self‐desorption dissolution electrolyte. With highly active sites pre‐protected, exhibits striking NH yield rate 55.1 µg h −1 mg cat Faradaic efficiency (FE) 66.5% alkaline media, exemplified representative application example. Moreover, it found prepared tolerate thermal environment, higher 75 at 60 °C recorded. Undoubtedly, these findings pave way broader BP .
