Abstract

Cu/H3BTC MOF was successfully synthesized. The prepared material was evaluated for dye degradation, oxidation of organic pollutants and epinephrine.

Synthesis, Catalytic Properties and Application in Biosensorics of Nanozymes and Electronanocatalysts: A Review

“…Cu/H 3 BTC MOF was used for quantitative detection of epinephrine. This NZ showed excellent stability under different conditions compared with natural laccase [258] (Figure 11).…”

“…Ren and other authors [254][255][256][257] reported one-pot synthesis of copper-containing carbon dots as laccase mimics. Shams and coauthors [258] described the synthesis of Cu/H 3 BTC MOF (copper ions with 1,3,5-benzene tricarboxylic acid, H 3 BTC and metal-organic framework, MOF) possessing laccase-like activity with regard to oxidation of phenolic compounds. Cu/H 3 BTC MOF was used for quantitative detection of epinephrine.…”

Facile synthesis of Cu/Ls MOF for laccase-like oxidative decomposition of phenols and identification of toxicity effects for C. elegans

“…The spectrum of the Ls featured a characteristic peak at 1616 cm − 1 , due to the asymmetric stretching vibration of the carboxylate moiety, along with symmetric stretching vibrations at 1402 cm − 1 (Li et al, 2018). The splitting of the broad C = O asymmetric stretching vibration band at peaks 1616 cm − 1 re ected the formation of Cu-O coordination (1598 and 1660 cm − 1 ) (Liang et al, 2017;Shams et al, 2019). The FTIR spectrum of Cu/Ls MOF in the wavelength range of 4000 − 500 cm − 1 con rmed that the Cu/Ls MOF was formed through the coordination of Ls with Cu ions (Fig.…”

“…Starting from these studies, when investigating laccase mimics, we observed that Ls formed complexes with Cu ions and then could effectively catalyze the reaction of phenol derivatives with oxygen. Since laccases can catalyze the oxidation of various compounds containing phenolic structures (Su et al, 2018), enzyme-mimicking catalysts have received attention as possible replacements of natural enzymes in the eld of environmental science (Liang et al, 2017;Shams et al, 2019). In amide-containing surfactants, the amide group is an easily accessible source of electrostatic, H-bonding and hydrophobic interaction forces (Perinelli et al, 2020), that provides the basis for the construction of different complexes.…”

Current research progress on laccase-like nanomaterials

“…The active centers of natural laccase are copper ions. Recently, a number of copper-based nanomaterials, such as copper-nucleotide/DNA coordination compounds, 46–51 copper-amino acid/peptide/protein coordination compounds, 52–56 and other copper-based nanomaterials, 57–62 have been developed to simulate laccase activity. Besides copper-containing nanomaterials, other metal-based nanomaterials have been found to have laccase activity, for example, platinum nanoparticles, 63 manganese oxides, 64 etc.…”
