Metal-organic framework composites have the advantages of large surface area, high porosity, strong catalytic efficiency and good stability, which provide a great possibility of finding excellent electrode materials for electrochemical sensors. However, MOF composites still face various challenges and difficulties, which limit their development and application. This paper reviews the application of MOF composites in electrochemical sensors, including MOF/carbon composites, MOF/metal nanoparticle composites, MOF/metal oxide composites and MOF/enzyme composites. In addition, the application challenges of MOF composites in electrochemical sensors are summarized. Finally, the application prospect for MOF composites is considered to promote the synthesis of more MOF composites with excellent properties.

In this study, we synthesized two nanocomposites, cross-linked PVA/HKUST and PVA/ZIF-67, by integrating metal-organic frameworks (MOFs) into electrospun polyvinyl alcohol (PVA). Several characterization techniques including FTIR, XRD, ICP, SEM, TGA, UV-Vis, zeta potential, and N adsorption-desorption were employed. The adsorption performance of the composites for cefixime (CFX) removal was assessed under varying conditions such as MOF content, contact time, pH, initial CFX concentration, and temperature.

Transition metal sulfides (TMSs) have significant potential in energy storage applications due to their high theoretical capacity and diverse reaction mechanisms. However, performance limitations in supercapacitors arise from various intrinsic defects, including low active material utilization and poor cycling stability caused by unstable electrical conductivity. To address these issues, this paper incorporates selenium atoms into sulfides, aiming to leverage selenium's high conductivity to enhance the electroactivity of transition metal sulfides.

The integration of metal-organic frameworks (MOFs) with functional materials has established a versatile platform for a wide range of energy storage applications. Due to their large specific surface area, high porosity, and tunable structural properties, MOFs hold significant promise as components in energy storage systems, including electrodes, electrolytes, and separators for alkali metal-ion batteries (AIBs). Although lithium-ion batteries (LIBs) are widely used, their commercial graphite anode materials are nearing their theoretical capacity limits, and the scarcity of lithium and cobalt resources increases costs.

Clean energy conversion and storage require simple, economical, and effective electrode materials to achieve promising results. The development of high-performance electrocatalysts with adequate stability and cost-effectiveness is essential to ensure low overpotentials toward the oxygen evolution reaction (OER). Herein, a cobalt-based metal-organic framework with 4,4,4-6T14 topology in combination with various ratios of NiMn-layered double hydroxide (Co-MOF@%NiMn-LDH, = 5, 10, 20, and 40%) is applied as an effective electrocatalyst for the oxidation of water.

The oxygen evolution reaction (OER) is hindered by slow kinetics due to its four-electron process, limiting overall efficiency. The rational design of metal-organic framework (MOF)-based nanomaterials is crucial for enhancing the oxygen production rate. Using a straightforward strategy, we synthesized cobalt-iron layered double hydroxide (CoFe-LDH) hollow polyhedra loaded with CeO, with zeolite imidazolate framework-67 (ZIF-67) serving as the precursor.
