“…To impart high sensitivity and some chemical specificity not available at the unmodified electrode, the electrode surfaces were widely modified with various materials. Recently, some groups have attempted to detect trace amounts of compounds using MOF bulk crystals with electrocatalytic activity for modification on the electrode surfaces because of their naked active sites, high surface areas, specific adsorption affinity and various pore sizes . In addition to the direct modification of single component MOFs on the electrode surfaces, the introduction of other highly conductive and mechanically durable materials in MOFs has been developed to overcome the disadvantages such as poor stability in water, low electronic conductivity, and unsatisfactory electrocatalytic ability.…”

“…The high electrocatalytic activity of the Cu‐MOF modified electrode was explained by the electron transfer process of Cu(II)‐MOF/Cu(I)‐MOF couple. Similarly, a Cu‐MOF modified carbon paste electrode and a Cu‐MOF electrodeposited on a copper plate as amperometric detectors were fabricated for the detection of 2,4‐dichlorophenol and bromate, respectively ,. The above Cu‐MOF modified electrodes showed high sensitivity and high stability for the analytes owing to excellent electrocatalytic ability of Cu‐MOFs and effective immobilization of MOFs on the electrode surfaces.…”

frameworks (MOFs), synthesized by assembling metal nods with organic linkers, are highly ordered crystalline materials. MOFs have attracted much attention for applications in electrochemical sensors, because of their unique chemical and physical properties including ultrahigh porosity, large surface area, tunable structure, and high thermal and chemical stability. In particular, redox and catalytic active sites introduced by use of active metal ions and/or ligands endow MOFs with the functions required in electrochemical sensing. Moreover, precise chemical modification of functional molecules and immobilization with metal nanoparticles, carbon nanostructures, and biomolecules could promote their electrochemical performances. In this Review, we focus on recent progress achieved in MOF research with respect to general sensing principles and analytical performances of electrochemical sensors. The evaluation and challenges governing the detection of the assays are also discussed.

As a class of metal-organic frameworks (MOFs) formed by association of metal cations Cu 2+ with organic ligands benzene tricarboxylic acid, HKUST-1 [1] and its derivatives have attracted much concern as they possess highly porosity, ultrahigh surface area, and the tunable structure which show its potential in various applications. Unlike other porous materials like graphene (GN), [2] multiple layers of carbon nanotube (MCNT), [3] In recent decades, metal-organic frameworks (MOFs) have achieved rapid development owing to the considerable concern from researchers. As one of the most intensely studied MOFs, HKUST-1 has shown remarkable performance which is considered feasible to apply in actual applications. However, the weak mechanical properties and water instability hinder its development which are mainly ascribed to lattice defects and surface barriers that impede mass transfer and molecular diffusion as well as electronic transmission. This review summarizes the recent literatures on the strategies of enhancing the above defects of virgin HKUST-1 and its various applications, mainly adsorption and separation, catalyst, sensor as well as optical and electronic applications. These improving strategies improve specific properties of HKUST-1 by decreasing the defects density, which will make this material more applicable for potential fields. Main strategies include the following: (1) modifying HKUST-1 with an "armor," (2) getting durable MOFs by direct synthesis or surface hydrophobization, (3) reconstructing the moisture-degraded HKUST-1, and (4) making use of the buffer action of sacrificial bonds. . His current research focuses on metal-organic frameworks (MOFs), porous coordination polymers (PCPs), morph-genetic MOFs, biomimetic functional composite, nanomaterials, materials for energy and environment, photoelectric functional materials, and so on.

“…[14][15][16] It could be suggested that enzyme-based electrochemical sensors have been received a comprehensive attention due to their high sensitivity, strong specificity, and excellent efficiency in the last few years. 23 There is no doubt that these nonenzymatic CPs sensors possess high specificity and long-term stability. Therefore, nonenzymatic electrochemical sensors constructed by various nanomaterials have been proposed as promising alternatives in recent years.…”

Herein, a facile and enzyme-free CP sensor was fabricated by in situ electrochemical reduction strategy on the surface of glassy carbon electrode (GCE). Reduced graphene oxide (RGO) was chose as supporting materials for the distribution of platinum nanoparticles (Pt NPs) to obtain improved catalytic properties. The applicability and suitability of the obtained RGO-Pt/GCE for 4-CP detection were also evaluated. The results indicated that the RGO-Pt NPs modified electrode displayed much better catalysis and higher sensitivity for 4-CP oxidation. Under optimum conditions, the oxidation peak current was proportional to 4-CP concentration in the range from 0.1 to 500 μM with a detection limit of 51 nM. Meanwhile, it is demonstrated that the prepared sensor is also characterized by excellent feasibility, satisfactory reproducibility, good stability and high specificity. The results suggested that RGO-Pt/GCE could be a facile, costeffective, and rapid tool for the prospect on-line evaluation of 4-CP in drinking water samples.
