Modularly aromatic-knit graphitizable phenolic network as a tailored platform for electrochemical applications

Abstract

Polyphenols hold tremendous potential for various electrochemical applications due to their non-covalent bonding-based simple coating process and high compatibility with chelating active metallic species. However, polyphenols are intrinsically prone to...

Tannic Acid-Derived Carbon Coating on LiFePO4 Nanocrystals Enables High-Rate Cathode Materials for Lithium-Ion Batteries

“…This further demonstrated that TA interacts with LiFePO 4 during the coating process. 16 The interaction mechanisms of TA and LiFePO 4 are schematically shown in Figure S4b. After pyrolysis at 650 °C, the characteristic peak of TA disappeared.…”

“…13−15 In contrast, conventional carbon sources without TA-like chelating abilities, such as glucose, sucrose, and starch, always require stirring or grinding to improve their coating uniformity. Moreover, as a plant polyphenol, TA is widely found in various trees, shrubs, and other plants with extensive resources 16 and is a low-cost carbon source for coating LiFePO 4 nanocrystals in an environmentally benign manner.…”

Pomegranate seed polyphenol-based nanosheets as an efficient inhibitor of amyloid fibril assembly and cytotoxicity of HEWL

“…It worth to note that, decarboxylation of compounds and decomposition of estercontaining polyphenols during the process would diminish the possibility of polyphenols self-condensation. 36 But, that's not the whole story, the phenoxy radicals formed in polyphenols structure show a resonance in which the radical character is localized on the ortho-and para-carbons as well as the phenolic oxygen, which can lead to self-condensation of polyphenols via the C-O and C-C bonds. 37 The charge densities calculations have revealed that 41.3% and 39.1% of the spin densities are located on the phenolic and para-carbons, respectively, 38 indicating that the polyphenols are mostly self-condensed through these two sites.…”

A Novel Tannic Acid-Based Carbon-Supported Cobalt Catalyst for Transfer Hydrogenation of Biomass Derived Ethyl Levulinate

“…Cobalt-based catalysts are excellent catalysts for biomass transfer hydrogenation using isopropanol as hydrogen source and solvent. Most of the reported supported catalysts prepared from cobalt and tannic acid were used for the hydrogenation of the halogenated aromatic or the degradation of dyes ( Wang et al, 2020 ; Choi et al, 2021 ; Varila et al (2021) . To the best of our knowledge, the direct use of tannic acid derived carbon supported transition metal cobalt catalysts for the CTH reaction of EL has not been reported.…”
