“…All the synthesized catalysts’ morphologies were also studied through SEM (scanning electron microscopy) analysis illustrated in Figure 4 . SEM images show clear incorporation of NiO/CuO MOF nanosheets stacked over each other within the wrinkled sheets of rGO [ 48 , 49 ]. While EDX results in Table 1 depicts the presence of nickel and copper along with carbon and oxygen.…”

In this work a novel bimetallic nickel oxide/copper oxide metal–organic framework (NiO/CuO MOF) has been developed by using two linkers: Benzene Dicarboxylic acid (BDC) and Pyrazine. The composites of NiO/CuO MOF with different amounts of reduced graphene oxide (rGO) were synthesized through a hydrothermal method and subsequently characterized by multiple significant techniques like XRD, SEM, EDX, FTIR and Raman IR for an investigation of their structural and morphological properties. The prepared series of material was later employed for electrochemical oxidation of methanol, tested by cyclic voltammetry (CV) in basic medium on a modified glassy carbon electrode (GCE). The electrochemical response depicts that increasing concentration of rGO enhances the electrocatalytic activity of the catalyst for methanol oxidation reaction (MOR). The catalyzed oxidation reaction of methanol by NiO/CuO MOF and rGO-NiO/CuO MOF composites give a superlative current density of 437. 28 mA/cm2 at 0.9 V potential at 50 mV/s scan rate. This activity makes it a promising catalytic material for electrolysis of methanol in direct methanol fuel cell (DMFC).

“…Developing novel, fast and highly sensitive electrochemical biosensors for pesticides and food safety is a major goal for future electroanalysis [22]. Reduced graphene oxide represents a class of carbonbased materials that have been extensively used in electroanalysis for hormones [23,24], antibiotics [25,26] and biosensing [27,28], due to their high electrocatalytic activity, remarkable electronic transport properties and large surface area [29][30][31][32]. The main point of this article is to describe the preparation, characterization and application of an electrochemical biosensor based on reduced graphene oxide for the immobilization of AChE, and its application for carbaryl detection in food samples.…”

Food safety is a major concern for human health and wellbeing all over the world. A novel and sensitive biosensor based on reduced graphene oxide (rGO) and the enzyme acetylcholinesterase (AChE) was developed and applied for the detection of carbaryl in food samples. The glassy carbon/rGO/AChE biosensor was characterized morphologically and electrochemically using scanning electron microscopy and cyclic voltammetry/electrochemical impedance spectroscopy, respectively. Optimum differential pulse voltammetry conditions led to a nanomolar detection limit, and determination of carbaryl in tomato was achieved.

“…2e and f. The surface morphology of GO and rGO features a layered structure with a wrinkled surface and relatively edge-folding [39]. Likewise, ultrathin paper-like morphology was observed for both samples, measuring the length of over several micrometers as to look so transparent [39,40].…”
