Summary: This study focuses on the ligand-engineering strategy to optimize the electronic structure of Ni-MOFs by incorporating electron-rich ferrocene unit. The resulting Ni-MIL-53-Fc shows significantly enhanced electrochemical oxygen evolution reaction (OER) activity compared to Ni-MIL-53-NH2, with a 6.6-fold improvement in TOF value at an overpotential of 350 mV. Characterizations further confirm that the introduction of Fc unit enhances charge transfer, leading to more electrons aggregated in the Ni active sites and improving the intrinsic OER activity of Ni sites. This ligand-engineering strategy can be extended to fabricate highly active and stable catalysts for other electrocatalytic reactions.

Summary: This study successfully achieves the heterogenization of homogeneous Ni-based molecular catalyst with the solid Fe-MIL-53-NH2 framework by covalently grafting, effectively integrating the advantages of homogeneous and heterogeneous catalysis. Electrochemical results indicate that the overpotential in NiN2Cl2@Fe-MIL-53 for the oxygen evolution reaction (OER) is significantly lower than that in Fe-MIL-53-NH2, confirming the key active sites of the Ni-based molecular catalyst. Kinetic analysis shows that the Eapp in the Ni-based molecular catalyst is much lower than that in NiN2Cl2@Fe-MIL-53, demonstrating the improved OER activity by regulating the rate-determining step with the incorporation of the Ni-based molecular catalyst.

Summary: In this study, ternary M-NiMOF (M = Co, Cu) materials were designed through a simple self-templated strategy, where Co/Cu MOF isomorphically grows in situ on the surface of NiMOF, forming a multivariate MOF.

Summary: Metal-organic frameworks (MOFs) have shown promising potential as electrode materials for the oxygen evolution reaction (OER). This study revealed that MOFs with tetrahedral Co sites exhibit continuous active sites in the OER, while those with octahedral sites are inert. Co-N coordination is more favorable for electrochemical activation than Co-O coordination, leading to the gradual increase in activity of the MOF in the OER process.

Summary: In this study, a facile chemical etching strategy was used to fabricate a one-dimensional hierarchical nanorods array composed of CoFe layered double hydroxide/metal-organic frameworks on carbon cloth, serving as efficient and stable catalysts for oxygen evolution reaction (OER) and urea oxidation reaction (UOR). The resulting catalyst exhibits large active surface area, enhanced conductivity, and extended electron/mass transfer channels, which are beneficial for catalytic reactions. Additionally, the intimate contact between CoFe LDH and MOFs modulates the local electronic structure of the catalytic active site, leading to enhanced adsorption of oxygen-containing intermediates to facilitate fast electrocatalytic reaction.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
