A novel bimetallic MOFs combined with gold nanoflakes in electrochemical sensor for measuring bisphenol A

Abstract

This work demonstrated the fabrication of bimetallic Fe–Cu-BTC which able to provide large surface area, good electrocatalytic efficiency in combination with gold nanoparticles (flakes shapes) in order to detect bisphenol A in water samples.

A Comparison Study of M-CuBTC MOFs (M: Fe, Zr) for Electrochemical Detection of Glyphosate

“…1a,b,c). CuBTC with more clear octahedral crystals were formed [23,25], while Fe-CuBTC clusters of those grains were likely to combine into larger particles [23]. SEM images of CuBTC and Zr-CuBTC samples with size 5-8 µm, octahedral crystals (Fig.…”

“…The synthesis of Fe-CuBTC was presented in [23] and it can be summarized as follows: 12 mmol of H 3 BTC were added to 60 mL of NaOH 1M solution and stirred vigorously until a clear solution (solution A) was obtained. A volume of 9.6 mmol FeCl 3 .6H 2 O was added to 40 mL of distilled water to form solution B, and 2.4 mmol of CuCl 2 .2H 2 O was added to 20 mL of distilled water to form solution C. Solutions B and C were mixed (molar ratio Fe : Cu = 8 : 2) and sonicated for 30 min to form a homogeneous solution (Mixture 2).…”

A highly-sensitive portable electrochemical sensor based on MWCNTs functionalized Au@Cu-MOF for environmental hormone bisphenol A

“…What's more, Mahnashi discovered that Ag@Cu-MOF offers an expanded surface area and serves as an exceptional site for electron transfer [14]. More importantly, gold nanoparticles are integrated into the bimetallic Fe-Cu-BTC to enhance its performance as an electrochemical sensor for bisphenol A [15]. Also, a nanocomposite, denoted as Au/Cu-MOF/SWNH, was synthesized by depositing gold nanoparticles onto single-walled carbon nanohorn-decorated copper MOF (Cu-MOF/SWNHs) [16].…”

Exploring the potential of ZnO–Ag@AgBr/SBA-15 Z-scheme heterostructure for efficient wastewater treatment: synthesis, characterization, and real-world applications

“…Phenolic compounds nd widespread use in various industries, including the production of dyes, pesticides, solvents, explosives, and other industrial precursors. [1][2][3] However, even in small amounts, these compounds can pose a threat to the environment and human health. 4 To remove such toxic compounds, several techniques like adsorption, catalysis, ozonation, Fenton or photo-Fenton, persulfateoxy oxidation, enhanced oxidation (AOP), and photocatalysis have gained signicant research interest.…”
