This study presents a facile strategy for synthesizing in situ N-doped Fe2O3 from iron nitride to tune its band structure photocatalytic applications. XRD analysis confirms the structural formation α-Fe2O3, while XPS verifies nitrogen incorporation of 8.87% and 5.52% obtained by oxidizing at 450 °C 550 °C, corresponding high-doped low-doped (HD-FO LD-FO) systems. FESEM BET showed that N-doping influenced particle aggregation, surface area, porosity, with bare (FO) exhibiting highest area (43.9 m2/g), followed HD-FO (34.39 m2/g) LD-FO (25.79 m2/g). UV-vis valence XPSs revealed bandgap narrowing 2.80 eV 2.71 (LD-FO) 2.53 (HD-FO), improving visible light absorption. Mott-Schottky plots more negative conduction potentials (-0.46 eV) (-0.54 compared FO (-0.39 eV), indicating enhanced electron transfer properties Photocatalytic RhB degradation under sunlight achieved ∼97%, 90%, 87%, H2 production rates 839.6, 749.4, 656.9 µmol g-1 h-1 LD-FO, HD-FO, FO, respectively.

Developing cost-effective electrocatalysts for efficient seawater splitting requires a fundamental understanding of the oxygen evolution reaction (OER) mechanism. Herein, iron-doped nickel phosphide (Fe-Ni2P) is synthesized via hydrothermal-impregnation-phosphidation strategy to investigate role Fe incorporation in modulating electronic structure and OER pathways. Mechanistic investigations demonstrate that doping triggers shift from adsorbate mechanism (AEM) lattice oxygen-mediated (LOM) pathways, evidenced by pH-dependent kinetics, tetramethylammonium cation probing, situ electrochemical impedance spectroscopy (EIS). The LOM involves nonconcerted proton-electron transfers, facilitated accelerated hydroxide adsorption (ks = 0.275 s-1) dynamic surface reconstruction into amorphous NiOOH. reduced activation energy (27.1 kJ mol-1) lower charge-transfer resistance Fe-Ni2P underscore its superior thermodynamics kinetics. X-ray photoelectron EIS further validate vacancy accumulation during process. Electrochemical studies reveal exhibits low overpotential 220 mV at 10 mA cm-2 remarkable stability through phosphate-mediated Cl- repulsion involving alkaline seawater. This work establishes Fe-induced modulation as critical activating LOM-dominated catalysis transition metal phosphides.

Abstract Fluorine (F) has emerged as a critical dopant for enhancing the performance of hematite (Fe 2 O 3 ) photoanodes in photoelectrochemical (PEC) water oxidation; however, its functional mechanisms remain to be fully elucidated. This study systematically demonstrates that F‐doping improves Fe ‐based through dual effects involving increasing charge carrier density electron structure modulation and activating lattice oxygen oxidation mechanism by optimizing intermediate adsorption. The are strongly correlated with improved separation efficiency injection across series (oxy)hydroxide/F‐Fe photoanodes. These optimally integrated into F‐NiFe/F‐FeOOH/F‐AlOOH/F‐Fe architecture, where precisely aligned hole‐trap energy levels enable exceptional (4.04 mA cm −2 at 1.23 V RHE , applied bias photon‐to‐current = 0.62%). work provides novel insights F doping proposes an design strategy impact, advancing field PEC splitting.
