“…The charge and discharge lifetime values in the acid and base mediums were 85 and 456 s, respectively. This confirmed the non-linear curves and change in behavior in the base medium [22][23][24]. The formation of the OHgroup caused increasing negative charge on the supercapacitor electrode that enhanced the pseudocapacitance properties of the prepared supercapacitor.…”

Graphitic carbon nitride (G-C3N4) was synthesized through the direct combustion of urea in the air. The CoS-Co2O3/G-C3N4 composite was synthesized via the hydrothermal method of G-C3N4 using cobalt salts. The morphological and chemical structures were determined through XRD, XPS, SEM, and TEM. XRD and XPS analyses confirmed the chemical structure, function groups, and elements percentage of the prepared nanocomposite. SEM measurements illustrated the formation of G-C3N4 sheets, as well as the flower shape of the CoS-Co2O3/G-C3N4 composite, evidenced through the formation of nano appendages over G-C3N4 sheets. TEM confirmed the 2D nanosheets of G-C3N4 with an average width and length of 80 nm and 170 nm, respectively. Two symmetric electrodes for the supercapacitor from the CoS-Co2O3/G-C3N4 composite. Electrochemical measurements were carried out to determine the charge/discharge, cyclic voltammetry, stability, and impedance of the prepared supercapacitor. The measurements were carried out under acid (0.5 M HCL) and basic (6.0 M NaOH) mediums. The charge and discharge lifetime values in the acid and base medium were 85 and 456 s, respectively. The cyclic voltammetry behavior was rectangular in a base medium for the pseudocapacitance feature. The supercapacitor had 100% stability retention up to 600 cycles; then, the stability decreased to 98.5% after 1000 cycles. The supercapacitor displayed a specific capacitance (CS) of 361 and 92 F/g, and an energy density equal to 28.7 and 30.2 W h kg−1 in the basic and acidic mediums, respectively. Our findings demonstrate the capabilities of supercapacitors to become an alternative solution to batteries, owing to their easy and low-cost manufacturing technique.

“…For this purpose, electrochemical polymerization was one of the most convenient techniques resulting in a thin polymer film in the redox reaction, which was more uniform and adherent on the surface [ 14 , 15 ]. Many monomers were used for electrochemical polymerization due to the high electron transfer efficiency and low cost, such as dyes, amino acids, and so on [ 16 , 17 ].…”

Olivetol is an important polyphenol compound and intermediate in the synthesis of cannabinoids possessing many types of biological activities. A facile electrochemical sensor for olivetol was fabricated based on p-L-serine, and copper oxide (CuO) nanoparticles modified carbon paste electrode (p-L-serine/CuO/CPE). The proposed p-L-serine/CuO/CPE was applied to the electrochemical detection of olivetol by cyclic voltammetry (CV) and differential pulse voltammetric (DPV). Through the characterizations of materials and modified electrodes, the p-L-serine/CuO/CPE exhibited enhanced electrochemical signals for olivetol compared to bare CPE and CuO/CPE in both CV and DPV methods. Under the optimized conditions, the proposed p-L-serine/CuO/CPE showed a good quantitative analysis ability and a wide analysis range from 20 to 100 μmol L−1 of olivetol with a limit of detection of 1.04 μmol L−1. Based on the reproducibility, repeatability, and stability exhibited by this fabricated sensor and the cheap and accessible raw materials, the p-L-serine/CuO/CPE became a novel determination choice for olivetol in the electrochemical method with the advantages of being cost-effective and convenient.

Conducting polymer-based inorganic/organic nanocomposites has become a popular candidate as eco-friendly thermoelectric (TE) materials in the past few years. This work reports a comprehensive study of the TE properties of tin sulfide (SnS)/polypyrrole (PPy) nanocomposites for the first time. The nanocomposites are prepared via two, low-cost steps: a chemical reaction to synthesize the SnS nanoparticles, followed by an in situ polymerization reaction. The TE properties of these SnS/PPy composites in a temperature interval of 303–373 K are investigated by tuning the content of SnS nanoparticles in the polymer matrix. The observations are discussed based on the results from structure analysis (X-ray diffraction), optical properties (UV–vis), surface morphology analysis (field emission scanning electron microscopy and high-resolution transmission electron microscopy), and chemical composition analysis (Fourier transform infrared spectroscopy, energy dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy). In order to analyze the orbital contribution and the carrier transport mechanism in the SnS/PPy composites, first-principles density functional theory (DFT) calculations are employed. The electronic band structure and density of states spectra clearly dictate that the formation of nanocomposite results in a decrement in the band gap, which might be a reason for the enhanced TE response of the nanocomposites. TE parameters, such as Seebeck coefficient (S), electrical conductivity (σ), and power factor (PF), are enhanced in the composites than in the pure PPy. The study reports maximum S (∼50.67 μV K–1), σ (∼32.26 S cm–1), and PF (∼6 μW m–1 K–2) values for composites containing 20, 10, and 20 wt % of SnS nanoparticles. Among the synthesized samples, the maximum ZT of ∼0.86 × 10–2 is achieved for PPy/20 wt % SnS at 373 K. This work concludes that the inclusion of SnS nanoparticle fillers in the conductive PPy matrix is an efficient route to enhance the TE performance of PPy. The newly fabricated nanocomposite is a novel, low-cost, nontoxic TE material relevant to green energy generation and environmental remediation.
