Tailoring Metal–Organic Frameworks and Derived Materials for High-Performance Zinc–Air and Alkaline Batteries

“…Figure S4 displays the XRD pattern of the Ni-MOF that consists of very sharp peaks and relatively high crystallinity, providing evidence for the successful formation of the Ni-MOF. The observed pattern (Figure S4) matches perfectly with the simulated pattern of the Ni-BDC (BDC = 1,4-benzenedicarboxylate) MOF (CCDC: 638866). − The diffraction peaks of the as-synthesized LDH, located at 2θ values of 11.61, 22.88, 33.45, and 34.82° are indexed to the (003), (006), (009), and (012) plane reflections, respectively, which are in accordance with the patterns of the hydrotalcite-like materials (Figure S4). In addition, the doublet diffraction peaks located at the 2θ value of ∼60°, corresponding to the Miller indices of (110) and (113), are characteristic peaks of the LDH structures and confirm the appropriate synthesis of LDH. ,, The presence of all of the diffraction peaks related to MOF and LDH in the XRD pattern of the MOF-LDH nanocomposite demonstrates the coexistence of the MOF and LDH structures in the synthesized nanocomposite.…”

“…The peaks located at 1064 and 777 cm –1 are the characteristic peaks of C–N and C–H, respectively. In addition, the peaks at 665, 545, and 470 cm –1 demonstrate the vibration of O–Ni–O . The broad band at 3470 cm –1 and the peak at 1635 cm –1 in the LDH spectrum demonstrate the vibration band of the −OH groups and the deformation vibration of H 2 O, respectively.…”

Hierarchical and ultra-porous copper cobaltite flakes with honeycomb-like physiognomies for highly efficient non-enzymatic glucose sensing

“…61 The stability of the sensor electrode over time is critical for improved practical and economic viability. 62 In this regard, the long-term stability of the glucose sensor was assessed by the amperometric measurements of the CuCo 2 O 4 electrode over a period of 30 days at a time interval of 5 days in a solution of 0.15 mol dm −3 NaOH solution containing 1 mmol dm −3 of glucose at an applied potential of 0.5 V, and the corresponding results (in histogram) are shown in Fig. 7(B).…”

“…69,70 In order to evaluate the potential use of a CuCo 2 O 4 based glucose sensor for practical applications in real sample analysis, glucose was detected in soft drink (coca-cola). 62 Fig. 7(D) displays the amperometric curve of CuCo 2 O 4 based sensor with continuous addition of 0.015 mmol dm −3 of soft drink (0.5% v/v).…”

Electrospun Manganese-Based Metal–Organic Frameworks for MnOx Nanostructures Embedded in Carbon Nanofibers as a High-Performance Nonenzymatic Glucose Sensor

“…29 Electrode materials with enhanced conductivity and a large specific surface area can promote electron transfer occurring at the electrolyte/ electrode interface, which is essential for the sensor's sensitivity and response time, and the electrode material should also have good biocompatibility. 30 Transition metal oxides, such as manganese oxide (MnO 2 ), 31−33 cobalt oxide (Co 3 O 4 ), 34−36 and nickel oxide (NiO), 37−39 have shown promise as electrocatalysts in various electrochemical applications, including sensing and biosensing. Among them, MnO 2 exhibits unique electronic and electrochemical properties that make it an attractive material for glucose sensor fabrication.…”
