“…They have attracted much interest because of their intriguing properties. − MOFs are emerging as advanced materials for a large variety of potential applications. − As one of the most studied MOFs, HKUST-1 ([Cu 3 (H 2 O) 3 (BTC) 2 ] n , BTC: 1,3,5-benzenetricarboxylate) has advantages of open metal sites, facile preparation, and high surface area . Many efforts have been focused on the development of applicable methods to synthesize MOFs including solvothermal, electrochemical deposition, layer by layer deposition, self-assembled monolayer and in situ growth . Among these, in situ growth is a simple and fast deposition method that includes multiple conversion steps.…”

Metal−organic frameworks (MOFs) have been previously investigated as electrode materials for developing electrochemical sensors. They have usually been reported to suffer from poor conductivity and improvement in the conductivity of MOFs is still a great challenge. Here, we reported the fabrication of an electrochemical sensor based on the in situ growth of framework HKUST-1 on conductive graphene oxide nanoribbons (GONRs)-modified glassy carbon electrode (GCE) (HKUST-1/ GONRs/GCE). The as-fabricated modified electrode was characterized using field emission scanning electron microscopy, transmission electron microscopy (TEM), high-resolution TEM, Fourier transform infrared, X-ray diffraction, electrochemical impedance spectroscopy, cyclic voltammetry, and Raman spectroscopy. The voltammetric response of HKUST-1/GONRs/GCE toward Imatinib (IMA), as an anticancer drug, is dramatically higher than HKUST-1/GCE because of the synergic effect of the GONRs and HKUST-1 framework. The calibration curve at the HKUST-1/GONRs/GCE for IMA covered two linear dynamic ranges, 0.04−1.0 and 1.0−80 μmol L −1 , with a detection limit of 0.006 μmol L −1 (6 nmol L −1 ). Taking advantage of the conductivity of GONRs and large surface area of HKUST-1, a sensitive modified electrode was developed for the electrochemical determination of IMA. The present method provides an effective strategy to solve the poor conductivity of the MOFs. Finally, the obtained electrochemical performance made this modified electrode promising in the determination of IMA in urine and serum samples.

“…Since the program can precisely control the relevant parameters such as the wetting time which ensures consistency, the obtained SURMOF surface topography has high flatness and can be mass-produced. In 2019, Esther [12] et al used the layer-by-layer liquid phase epitaxy method to form and characterize SURMOF on Au substrate which proves that the method is universal.…”

In recent years, MOF has been widely studied as new material. Due to its structure’s diversity, flexibility, and tunability, it is favoured by many scholars and has been used in many fields. However, due to the diversity of MOF types and the wide range of applications, there is a lack of systematic description of the application of MOF materials at present. This paper concluded several aspects of the application of MOF to close this loophole. In this paper, the preparation method including the gas-phase method, hydrothermal method, and liquid-phase epitaxy method of the MOF is introduced, then followed by the method of bringing metal nanoparticles into the prepared frame to make the doped MOF including the impregnation method and double solvent method, and then by adsorption, catalysis, and gas sensor, three aspects are briefly introduced MOF in these fields of application are introduced in these areas in different refining branch such as carbon monoxide adsorption, catalytic hydrogenation, and alkanes as nitric oxide gas sensor. Meanwhile, the challenges for this kind of material are long-term stability, heat resistance, and high cost. This paper is expected to summarize the application of MOF and hope it can bring more economic benefits and scientific value.

“…[25][26][27] In this regard, metal-Nheterocyclic carbene (NHC) complexes have shown great potential in catalysis due to their ease of preparation, modularity in stereoelectronic properties, and unique electronic stability. [28][29][30][31][32] Despite the extensive exploration and progress achieved in chemical catalysis of metal-NHC complexes, [33][34][35][36][37][38][39][40][41][42][43][44][45] investigating these complexes as enzyme mimics and subsequent utilization in biosensing is still in its infancy.…”
