“…We can also say that the decrease in peak current can be attributed to the forming of negatively charged functional groups on the surface of the P-doped/PGE and the electrostatic repulsion with Fe(CN) 6 3À /4À groups.

In this study; a sensitive, selective, and simple electrochemical sensor was developed to determine low concentration pyridoxine (Py) using a phosphorus‐doped pencil graphite electrode (P‐doped/PGE). Electrode modification was implemented using the chronoamperometry method at +2.0 V constant potential and 100 seconds in 0.1 mol L−1 H3PO4 supporting electrolyte solution. The characterization processes of the P‐doped/PGE were carried out using electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), X‐ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM), energy‐dispersive X‐ray spectroscopy (EDX), and atomic force microscope (AFM) methods. In the concentration study, using the differential pulse voltammetry (DPV) method, a linear calibration plot was acquired in the concentration range of 0.5 to 300 μmol L−1 Py. The limit of quantification (LOQ) and limit of detection (LOD) of the developed method were calculated as 0.219 μmol L−1 and 0.0656 μmol L−1, respectively. Detection of Py has been successfully performed on the P‐doped/PGE in the beverage samples. As a result, the method developed has been shown to have fast, low cost, and simple for the sensitive and selective detection of Py as an effective electrode.

“…While examples of the combination of PANI with metal oxides, NPs, carbon nanotubes, graphene, etc. are found in the literature, its combination with organic semiconductors such as phthalocyanines and porphyrins is less exploited [ 5 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. Examples of these PANI-macrocycle combinations dedicated to gas sensors are also rare [ 5 , 19 , 23 ].…”

We combined a conducting polymer, polyaniline (PANI), with an organic semiconducting macrocyclic (MCs) material. The macrocycles are the phthalocyanines and porphyrins used to tune the electrical properties of the PANI, which benefits from their ability to enhance sensor response. For this, we proceeded by a simple ultrasonically assisted reaction involving the two components, i.e., the PANI matrix and the MCs, to achieve the synthesis of the composite nanostructure PANI/MCs. The composite nanostructure has been characterized and deposited on interdigitated electrodes (IDEs) to construct resistive sensor devices. The isolated nanostructured composites present good electrical properties dominated by PANI electronic conductivity, and the characterization reveals that both components are present in the nanostructure. The experimental results obtained under gas exposures show that the composite nanostructures can be used as a sensing material with enhanced sensing properties. The sensing performance under different conditions, such as ambient humidity, and the sensor’s operating temperature are also investigated. Sensing behavior in deficient humidity levels and their response at different temperatures revealed unusual behaviors that help to understand the sensing mechanism. Gas sensors based on PANI/MCs demonstrate significant stability over time, but this stability is highly reduced after experiments in lower humidity conditions and at high temperatures.

“…In this context, the research on systems that store energy in chemical forms, such as rechargeable batteries (lead-acid batteries, redox ow batteries, lithium (Li)-ion batteries) and supercapacitors, has continues at an incredible pace. [4][5][6][7][8][9][10][11][12] Since lithium is the lightest metal, it is an extremely suitable candidate for use in rechargeable battery applications. This metal has been extensively researched for nearly half a century, and different Li-ion batteries with positive or negative electrodes consisting of lithium or lithium-containing compounds have been synthesized.…”
