“…As reported, 32 the cobalt nitrate hexahydrate (4 mmol) and 2‐methylimidazole (16 mmol) were dissolved in 50 mL of methanol separately. Then the 2‐MIM solution was mixed in the cobalt nitrate solution by continuous stirring on magnetic stirrer until the two solution were completely dissolved.…”

“…The manganese nitrate hydrate (4 mmol) and as‐synthesized ZIF‐67 were taken in 40 mL ethanol and then stirred for 30 minutes at rpm of 350 on magnetic stirrer. Then the material was collected by centrifugation, washed several times with ethanol and dried in vacuum oven at a temperature of 70°C for 6 hours 32 . The resultant light purple material was pyrolyzed in a tube furnace with the stay of 1 hour at 350°C and then the temperature was elevated to 700°C for 3.5 hours under H 2 /Ar atm (10/90).…”

In this study, the electrocatalytic activity of mono-metallic Co/NPC, bi-metallic MnCo/NPC, and ternary NiMnCo/NPC in alkaline media for the methanol oxidation process was examined (MOR). These materials were produced using a simple solution mixing method and characterized using FTIR, EDX, SEM, XPS, TGA, and XRD. In a three-electrode arrangement, on glassy carbon electrodes, the investigation of methanol oxidation for electrochemical activity of catalysts was carried in 1 M NaOH and 3 M CH 3 OH. Electrochemical studies included cyclic voltammetry (CV), chronoamperometry (CA), and electron impedance spectroscopy (EIS). The ternary NiMnCo/NPC composite, which has a peak current density of 147.85 mA/cm 2 at 0.8 potential and a scan rate of 50 mV/s among all the composites developed, is a promising catalyst for methanol electrocatalysis.

“…Xiaocong et al found that CoF 2 nanoparticles anchored on nitrogen‐doped carbon structure derived from ZIF‐67 show good OER performance 22 . Due to the presence of N carbon substrates, such as ZIFs, the carbon‐based catalysts obtained from ZIFs usually have N species in their graphite structure 23‐26 . These N atoms are also used to bond the metal atom 27,28 .…”

Principles of Design and Synthesis of Metal Derivatives from MOFs

et al. 2023

Materials derived from metal–organic frameworks (MOFs) have demonstrated exceptional structural variety and complexity and can be synthesized using low‐cost scalable methods. Although the inherent instability and low electrical conductivity of MOFs are largely responsible for their low uptake for catalysis and energy storage, a superior alternative is MOF‐derived metal‐based derivatives (MDs) as these can retain the complex nanostructures of MOFs while exhibiting stability and electrical conductivities of several orders of magnitude higher. The present work comprehensively reviews MDs in terms of synthesis and their nanostructural design, including oxides, sulfides, phosphides, nitrides, carbides, transition metals, and other minor species. The focal point of the approach is the identification and rationalization of the design parameters that lead to the generation of optimal compositions, structures, nanostructures, and resultant performance parameters. The aim of this approach is to provide an inclusive platform for the strategies to design and process these materials for specific applications. This work is complemented by detailed figures that both summarize the design and processing approaches that have been reported and indicate potential trajectories for development. The work is also supported by comprehensive and up‐to‐date tabular coverage of the reported studies.
