“…Among them, MIL-100(Fe) is used as a transition metal MOF, which has two different mesoporous cages (2.5 and 2.9 nm). It has high stability, a rigid zeotype crystal structure, biocompatibility, and a large number of coordinatively unsaturated metal sites [23], which makes it show promising applications in catalysis [24], adsorption and separation [25]. Furthermore, it is used in photocatalytic applications owing to its excellent optical properties [26] and as a carrier for drug delivery applications [27].…”

“…In general, a mixture of H 2 SO 4 (60 mL) and HNO 3 (20 mL), with a volume ratio of 3 to 1, was used to acidify and functionalize MWCNT (1.0 g) (MWCNTs-AO) [ 37 ]. An amount of 20 mg MWCNTs-AO, 1.32 mL PdCl 2 /DES solution (5 mg/mL), and 0.44 mL Ni(NO 3 ) 2 /DES solution (5 mg/mL) were added to 10 mL DES.…”

Herein, an electrocatalyst with Pd2Ni1 nanoclusters, supporting multiwalled carbon nanotubes (MWCNTs) (referred to Pd2Ni1/CNTs), was fabricated with deep eutectic solvents (DES), which simultaneously served as reducing agent, dispersant, and solvent. The mass activity of the catalyst for formic acid oxidation reaction (FAOR) was increased nearly four times compared to a Pd/C catalyst. The excellent catalytic activity of Pd2Ni1/CNTs was ascribed to the special nanocluster structure and appropriate Ni doping, which changed the electron configuration of Pd to reduce the d-band and to produce a Pd–Ni bond as a new active sites. These newly added Ni sites obtained more OH− to release more effective active sites by interacting with the intermediate produced in the first step of FAOR. Hence, this study provides a new method for preparing a Pd–Ni catalyst with high catalytic performance.

“…The detection of the flavone baicalein in human urine was achieved at a GCE modified by Bi2O3 and CMWCNTs, with an LOD of 2.0 nM in the linear range from 0.01 to 15 µM [85] (Figure 11). The flavonol kaempferol in XinDaKang tablets was detected at an electrochemical sensor based on GCE modified with a nonocomposite consisting of MOF MIL-100(Fe), MWCNTs and PEDOT, and it showed a linear range from 50 to 1950 nM and an LOD of 13.2 nM [118].…”

Flavonoids represent a large group of aromatic amino acids that are extensively disseminated in plants. More than six thousand different flavonoids have been isolated and identified. They are important components of the human diet, presenting a broad spectrum of health benefits, including antibacterial, antiviral, antimicrobial, antineoplastic, anti-mutagenic, anti-inflammatory, anti-allergic, immunomodulatory, vasodilatory and cardioprotective properties. They are now considered indispensable compounds in the healthcare, food, pharmaceutical, cosmetic and biotechnology industries. All flavonoids are electroactive, and a relationship between their electron-transfer properties and radical-scavenging activity has been highlighted. This review seeks to provide a comprehensive overview concerning the electron-transfer reactions in flavonoids, from the point of view of their in-vitro antioxidant mode of action. Flavonoid redox behavior is related to the oxidation of the phenolic hydroxy groups present in their structures. The fundamental principles concerning the redox behavior of flavonoids will be described, and the phenol moiety oxidation pathways and the effect of substituents and experimental conditions on flavonoid electrochemical behavior will be discussed. The final sections will focus on the electroanalysis of flavonoids in natural products and their identification in highly complex matrixes, such as fruits, vegetables, beverages, food supplements, pharmaceutical compounds and human body fluids, relevant for food quality control, nutrition, and healthcare research.
