Investigation of electrocatalytic and photocatalytic ability of Cu/Ni/TiO2/MWCNTs Nanocomposites for detection and degradation of antibiotic drug Furaltadone

Abstract

In this manuscript, “Get two mangoes with one stone” strategy was used to study the electrochemical detection and photocatalytic mineralization of furaltadone (FLT) drug using Cu/Ni/TiO2/MWCNTs nanocomposites for the first time. The bi-functional nanocomposites were synthesized through a hydrothermal synthesis technique. The successfully synthesized nanocomposites were analyzed by various analytical techniques. The Cu/Ni/TiO2/MWCNTs nanocomposites decorated screen-printed carbon electrode (SPCE) exhibit a good electrocatalytic ability towards detection of FLT. Moreover, the electrocatalytic detection of FLT based on the nanocomposites decorated SPCE have high stability, lower detection limit, and excellent sensitivity of 0.0949 μM and 1.9288 μA μM−1 cm−2, respectively. In addition, the nanocomposites decorated SPCE electrodes performed in real samples, such as river water and tap water, the satisfactory results were observed. As UV–Visible spectroscopy revealed that the Cu/Ni/TiO2/MWCNTs nanocomposites had an excellent photocatalytic ability for degradation of FLT drug. The higher degradation efficiency of 75% was achieved within 45 min under irradiation of visible light. In addition, after the degradation process various intermediates are produced which is confirmed by GC–MS analysis. The excellent photocatalytic ability was improved to the dopant ions and restrictions of electron–hole pair.

A High Efficient Electrocatalytic Activity of Metal‐organic Frameworks ZnO/Ag/ZIF‐8 Nanocomposite for Electrochemical Detection of Toxic Heavy Metal Ions

“…The peak around 288.6 eV was conducted to OÀ C=O [36]. Figure 6c shows the high-resolution spectra of N 1s at 398.6 eV, 399.8 eV, and 400.9 eV correspond to pyridinic-N, pyr-rolic-N, and graphitic-N, respectively [37]. Figure 6d presents the zinc high-resolution spectra of Zn 2p 3/2 and Zn 2p 1/2 which are found at 1020.8 and 1043.2 eV, confirming the presence of Zn in the sample [38].…”

Hierarchical 3D Snowflake-like Iron Diselenide: A Robust Electrocatalyst for Furaltadone Detection

“…Previous literature reported that FLD is highly unstable in vivo and can be rapidly metabolized in the forms of 3-amino-5-morpholinomethyl-2-oxazolidinone, 1-aminohydantoin, 3-amino-2-oxazolidinone, and semicarbazide. , It has the potential to bind to tissue proteins with high affinity and generate long-lasting protein conjugates . FLD and its metabolites can cause potential carcinogenic, mutagenic, and teratogenic effects on all living organisms. , Due to the negative impact on humans and the environment, FLD has been strictly prohibited in the United States (Register, 2002), China (Regulation of Department of Agriculture of China, 2002), European Union (EU Council Regulation No. 1442/95/EC, 1995, EU Council Regulation No.…”

“…24 FLD and its metabolites can cause potential carcinogenic, mutagenic, and teratogenic effects on all living organisms. 25,26 Due to the negative impact on humans and the environment, Thailand (2002), and other countries from usage in foodproducing animals. 19,20,27 Despite the fact that there are numerous strict laws and regulations to regulate the usage of FLD, it is still legally manufactured and widely used in many countries around the world due to its low cost and high efficacy.…”

“…For example, Rajakumaran et al constructed a FeVO/p-rGO nanocomposite-based electrochemical sensor for the detection of FLD . Likewise, Vasu et al used a Cu/Ni/TiO 2 /MWCNT nanocomposite as an electrode-modified material for the ultrasensitive detection of FLD . Among the electrocatalysts of recent interest, two-dimensional (2D)-transition-metal selenides (TMSes) are regarded to be a promising material for next-generation electrochemical applications owing to their several advantages of high conductivity, suitable bandgap, acceptable chemical stability, abundant active sites, and excellent catalytic properties. − As one of the 2D TMSes, iron diselenide (FeSe 2 ) has attracted considerable attention as an electrocatalyst in various electrochemical applications due to its physicochemical properties. − …”

Mechanistic insight into the photocatalytic degradation of organic pollutants and electrochemical behavior of modified MWCNTs/Cu–Co3O4 nanocomposites

“…16 Over the past decades, inexpensive and environmentally friendly, relatively reproducible, and more stable large-scale synthetic routes have been sought. There are several approaches available concerning the physical and chemical processes of nano metal oxides including the one-step solid-state reaction at room temperature, 17 electrochemical method, 18 sonochemical method, 19 co-precipitation method, 20 ultrasonic spray pyrolysis, 21 thermal decomposition, 22 sol–gel technique, 23,24 chemical vapor deposition (CVD), 25 laser ablation, 26 arc discharge, 27 ball milling, 28 hydrothermal synthesis, 29,30 gel-combustion synthesis 31 and the use of organic complexes. 32–35 These methods, however, are either time-consuming or require costly instruments.…”
