Three-dimensional PEDOT composite based electrochemical sensor for sensitive detection of chlorophenol

l-Cysteine-Terminated Triangular Silver Nanoplates/MXene Nanosheets are Used as Electrochemical Biosensors for Efficiently Detecting 5-Hydroxytryptamine

“…Among them, E θ , R , F , T , α, K s , and Q , respectively, represent the formal potential, gas constant, Faraday constant, thermodynamic temperature, transfer coefficient, apparent rate constant, and consumed charge. In the completely irreversible oxidation process, the value of α is 0.5 …”

Two-dimensional material-based functional aerogels for treating hazards in the environment: synthesis, functional tailoring, applications, and sustainability analysis

“…3d, Tian et al synthesized UiO-66-NH 2 @PEDOT with core-shell structure on the surface of Zr-based metal organic skeleton (UiO-66-NH 2 ) by in situ polymerization of (3,4-ethylenedioxythiophene) (PEDOT). 104 The modified electrode composed of GA as the substrate material of UiO-66-NH 2 @PEDOT was used as an electrochemical sensor for the detection of 4-chloro-3-methylphenol (PCMC). In this case, PEDOT was used to enhance electrochemical sensing performance due to its excellent electrocatalytic activity and high conductivity.…”

Tunable construction of electrochemical sensors for chlorophenol detection

“…These advantages make GAs an efficient electron transfer network, which is ideal for electrochemical sensors by providing high electrocatalytic activity and abundant active sites. For example, GAs have been used to load nanostructured PEDOT 93 and in situ polymerized PPy 128 to detect CPs. The effective surface area for GAs/GCE can reach 0.103 cm 2 , which is superior to that of the bare GCE (0.066 cm 2 ).…”

“…The effective surface area for GAs/GCE can reach 0.103 cm 2 , which is superior to that of the bare GCE (0.066 cm 2 ). 93 The large surface area provides more active sites, which is crucial to the improvement of sensing performance. The combination of GAs and various active materials for the high-performance sensing of CPs is still in progress.…”

“…As shown in Fig. 11b, Tian et al 93 employed Zr-based MOFs (UiO-66-NH 2 ) as a template for in situ polymerization of PEDOT, which generated a core-shell nanostructure. After compositing with gas, the porous material thus fabricated is suitable for modification onto the GCE, which demonstrates a LOD of 0.2 mM for the detection of PCMCs.…”
