Doping metals and constructing heterostructures are pivotal strategies to enhance the electrocatalytic activity of metal–organic frameworks (MOFs). Nevertheless, effectively designing MOF-based catalysts that incorporate both doping multiphase interfaces poses a significant challenge. In this study, one-step Co-doped Co3O4-modified Ni-MOF catalyst (named Ni NDC-Co/CP) with thickness approximately 5.0 nm was synthesized by solvothermal-assisted etching growth strategy. Studies indicate formation Co–O–Ni–O-Co bond in NDC-Co/CP found facilitate charge density redistribution more than Co–O–Ni bimetallic synergistic effect NiCo NDC/CP. The designating achieved superior oxygen evolution reaction (OER) (245 mV @ 10 mA cm–2) robust long stability (100 h 100 1.0 M KOH. Furthermore, NDC-Co/CP(+)||Pt/C/CP(−) displays pregnant overall water splitting performance, achieving current cm–2 at an ultralow voltage 1.52 V, which is significantly lower commercial electrolyzer using Pt/C IrO2 electrode materials. situ Raman spectroscopy elucidated transformation NDC-Co Ni(Co)OOH under electric field.

Abstract Metal‐organic frameworks (MOFs) have emerged as promising oxygen evolution reaction (OER) electrocatalysts. Chemically bonded MOFs on supports are desirable yet lacking in routine synthesis, they may allow variable structural and the underlying structure‐activity relationship to be disclosed. Herein, direct MOF synthesis is achieved by an organic acid‐etching strategy (AES). Using π‐conjugated ferrocene (Fc) dicarboxylic acid etching agent ligand, a series of MFc‐MOF (M=Ni, Co, Fe, Zn) nanosheets synthesized metal supports. The crystal structure studied using X‐ray diffraction low‐dose transmission electron microscopy, which quasi ‐lattice‐matched with that metal, enabling situ growth.

Microwave thermotherapy (MWT) has shown great potential in cancer treatment due to its deep tissue penetration and minimally invasive nature. However, the poor microwave absorption (MA) properties of thermal sensitizer medical frequency band significantly limit effect MWT then weaken therapeutic efficacy. In this paper, a Ni-based multilayer heterointerface nanomissile MOFs-Ni-Ru@COFs (MNRC) with improved MA performance desired via introducing magnetic loss dielectric is developed for MWT-based treatment. The loading Ni nanoparticle MNRC mediates loss, band. formed by nanoengineering induces significant interfacial polarization, increasing enhancing generated performance. Moreover, strong range not only enhances MW but also facilitates electron energy transfer, generating reactive oxygen species (ROS) at tumor sites mediate dynamic therapy (MDT). strategy strengthening improve MWT-MDT provides direction expanding clinical application

Abstract The electrochemical N 2 oxidation reaction (NOR) using water and atmospheric represents a sustainable approach to nitric acid production; while, the parasitic oxygen evolution (OER) usually results in poor conversion selectivity of oxidation.
