Article Abstract
A series of Ni-MOF materials were synthesized via a simple hydrothermal method and can be employed as electrodes for supercapacitors (SCs). Different temperatures were selected to unveil the effect of temperature on the formation, structure, and electrochemical performance of Ni-MOF-x (x = 60, 80, 100, and 120). Ni-MOF-80 possessed a larger specific surface area with a cross-network structure formed on its surface. The synthesized Ni-MOF electrode delivered a specific capacity of 30.89 mA h g when the current density reached 1 A g in a three-electrode system. The as-fabricated Ni-MOF materials could be further designed and are expected to deliver satisfactory performance in practice.

Pre-designed core-shell metal-organic frameworks (MOFs@MOFs) with customized functionalities can enhance the material properties compared to conventional single MOFs. The porous carbon composites derived from MOFs@MOFs also have excellent functionality due to the presence of multiple metal/metal oxide nanoparticles. This paper synthesized a novel MOFs@MOFs composite (MIL-101(Fe)@Ni-MOF) with a core-shell structure with MIL-101(Fe) as the core and Ni-MOF as the shell.

The increasing demand for non-invasive and non-enzymatic glucose sensors is driven by the objective of eliminating the need for blood pricks from the body and enabling enzyme-free detection of glucose for diagnosing diabetes mellitus. To address this need, we synthesized Ni MOF-MXene (Ni) hybrid material through a one-pot synthesis method, which acts as a catalyst to detect salivary glucose using an extended gate field effect transistor (EGFET) method. The resulting sensor exhibits good selectivity towards glucose over common interfering molecules such as sucrose, fructose, maltose, uric acid, and ascorbic acid under physiological conditions in saliva.

Nickel MOF (Ni-MOF) nanoparticles were successfully anchored onto a polymeric graphitic carbon nitride (g-CN) and Chitosan nanostructure (NS) using an eco-friendly and straightforward synthesis method. These newly fabricated photocatalysts were thoroughly characterized with standard techniques, revealing that the nanoscale Ni-MOF particles were uniformly deposited on the sheet-like g-CN matrix. This configuration demonstrated excellent antimicrobial properties and outstanding photodegradation of tetracycline hydrochloride under visible light exposure.

The electric conductivity and charge transport efficiency of metal-organic frameworks (MOFs) dictate the effective utilization of built-in redox centers and electrochemical redox kinetics and therefore electrochemical performance. Reticular chemistry and the tunable microcosmic shape of MOFs allow for improving their electric conductivity and charge transfer efficiency. Herein, we synthesized two Ni-MOFs (Ni-tdc-bpy and Ni-tdc-bpe) by the solvothermal reaction of Ni ions with 2,5-thiophenedicarboxylic acid (Htdc) in the presence of conjugated 4,4'-bipyridyl (bpy) and 1,2-di(4-pyridyl)ethylene (bpe) coligands, respectively.
