Abstract 2D layered black phosphorus (BP), also known as phosphorene, has attracted significant attention for its potential applications in transistors, catalysis, biomedicine, energy conversion, and storage. However, addressing the reactivity of BP with oxygen water, thus achieving an effective passivation deprotection remains a key challenge. Here, we demonstrate protective strategy based on covalent functionalization chelation to passivate surface. This approach involves modification tannic acid (TA) reduce lone electron pairs BP, followed by Fe III ions TA yield shielding layer, thereby providing dual protection. protection confers exceptional stability allowing it remain stable over five months under ambient conditions. Furthermore, can be deprotected treatment weak acids ultrasonic conditions, restoring utilizing broader fields.

Abstract The carbon‐free electrocatalytic nitrogen reduction reaction (NRR) is an alternative technology to the current Haber‐Bosch method, that can be conducted under ambient conditions, and directly converting water (N₂) into ammonia (NH₃). However, limited activity selectivity of NH₃ electrosynthesis hinder practical applications NRR. In this study, we present a novel type electrocatalyst called boridene nanosheets enriched with metal vacancies are specifically designed for efficient NRR conditions. Electrochemical testing in 0.1 M phosphate‐buffered saline (PBS) electrolyte demonstrates exhibits high Faradaic efficiency 66.7 % production at −0.2 V vs. RHE, maximum yield rate 23.6 μg h −1 mg cat −0.4 RHE. Durability tests show maintains significant stability throughout multiple cycles Mechanistic insights obtained through situ Fourier transform infrared spectroscopy, revealing preference distal pathway during process These findings highlight potential as stable catalyst sustainable synthesis.
