Abstract Developing overall water splitting non‐noble metal electrocatalysts achieving long‐term stability with high activity at industrial‐grade current density remains challenging. Herein, a self‐reconstruction strategy of Co 9 S 8 ‐Ni 3 2 /NCF is employed to fabricate Ni x 3‐x O 4 ‐Ov‐ in which partial replaced by the structure. The reconstructed ‐Ov can enhance adsorbing ability leached from initial phase compared spinel, exceeding 1000‐h oxygen evolution reaction (OER) and 600‐h 1000 mA cm −2 excellent activity. In situ Raman X‐ray photoelectron spectroscopy (XPS) results indicate that substitution for atoms enhances adsorption capacity on ‐Ov, facilitating formation high‐density 3+ active sites (400) expedited interfacial electron transfer densities. Density functional theory (DFT) calculations reveal stabilizes surface vacancies optimizes energy intermediates, thereby improving both catalytic performance. findings provide new insights into overcoming activity‐stability trade‐off contribute design

MOF-based heterojunctions can significantly enhance the efficiency of photocatalytic hydrogen production; however, construction efficient remains a formidable challenge. In this study, we successfully developed series Type II by growing TiO2 on Cr-based MOF, thereby regulating generation, separation, and transportation photogenerated charge carriers to improve evolution performance. Among these, 23%TiO2/MIL-101(Cr) photocatalyst exhibited highest production activity, achieving 884.01 μmol g–1 in just 5 h, which is 6.8 6.0 times that pure MIL-101(Cr) TiO2, respectively. Additionally, demonstrated excellent cyclic stability. Tiny particles were proven mainly deposited surface N2 sorption isotherm analyses, transmission electron microscopy (TEM), high-resolution TEM, high-angle annular dark field scanning microscopy, etc. Characterization techniques such as situ XPS confirmed formation TiO2/MIL-101(Cr) heterostructure. Band structure analysis indicates meets thermodynamic requirements for production. Furthermore, transient photocurrent measurements, electrochemical impedance analysis, photoluminescence reveal possesses superior capabilities carrier transport, resulting from kinetic perspective. This research offers valuable insights into preparation development photocatalysts

Abstract Developing oxygen evolution reaction (OER) electrocatalysts in an efficient strategy, while maintaining high catalytic activity and stability under current densities, remains a crucial problem. In this study, bimetallic iron‐cobalt phytic acid complex loaded with polyaniline hollow structure (FCP@PAn) was successfully constructed, via progress of selective etching surface modification one step without high‐temperature phosphating or carbonization. The as‐obtained FCP@PAn required only 329 385 mV overpotentials at densities 500 1000 mA cm −2 , respectively, due to incorporation the coordinated effect each component. Additionally, exhibited lowest Tafel slope values 44.6 dec −1 able continuously operate for 120 h displaying stability. Hence, conductive polymer MOFs composites provided new strategy transition metal‐based catalysts that are prone dissolution corrosion during OER process, as well density applications.
