“…Cadmium Sulfide (CdS) serves as one of the most significant binary chalcogenides, which is used in different applications such as photosensors, solar cells, gas sensors, semiconductor lasers, electroluminescent photography devices, light-dependent resistances, vacuum ultraviolet (UV) optics, photocatalytic substances, pigment photovoltaic cells, paint industry, piezo transducers, and buffer material for different photovoltaic cells construction [1][2][3][4][5]. This is owing to its advantages: it is a type of semiconductor with an extensive band gap of 2.42 eV at ambient temperature (300 o K) [6], possesses hall transportation of the electrons ~104 cm 2 /V s, light transmission <70%, and excellent optical storage capacity [7].…”

Electrochemically synthesized cadmium sulfide (CdS) on cupper-modified substrate from an acidic solution containing Cd 2+ and S2O3 2ions at 20 o C has been produced with potentiostatic and potentiodynamic methods utilizing a three-electrode system. The prepared films have been characterized utilizing X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). X-ray diffraction analyses demonstrate that, under our optimized conditions, the CdS thin films deposited using both methods exhibit a pure and hexagonal structure. The electrodeposited CdS was found to behave as a p-type semiconductor, which was examined and demonstrated via the Mott-Schottky measurement. Depending upon the obtained data in this work, it was discovered that the electrodeposition techniques affect the morphology of the electrodeposited material (confirmed by SEM), carrier concentrations, thickness δSC of the space-charge layer, the energy gap (Eg), as well as the sensitivity towards CO2 electro-reduction.

In the present work, CdS nanoparticles were synthesized and analyzed for use in fuel cell applications. The X-ray diffraction investigation showed that CdS possesses a cubic polycrystalline structure. For the (111) plane, the average values of mean crystallite size, microstrain, and dislocation density were calculated and found to be 1.935 nm, 0.0758, and 0.267 nm−2. The average crystallite size was additionally calculated and found to be 2.02 nm using the modified Scherrer’s plot. The observed blue shift in the photoluminescence of CdS is caused by the quantum size impact of the nanocrystalline structure. A broad emission band at 590 nm is produced by the recombination of a hole in the valence band of CdS with an electron confined in a sulfur vacancy. The average Cd/S ratio is good and comparable, according to the EDS analysis, which is close to the theoretical values and almost exactly fits the ideal structure. A thermogravimetry diagram was used to establish the thermal stability of CdS across a wide range of temperatures. Fuel cell application features peaks were investigated by the cyclic voltammetry of CdS under various conditions. The linear sweep voltammetry was used to analyze the electrochemical performance of CdS electrodes in fuel cells. Electrochemical impedance spectroscopy (EIS) was also used and the results confirmed that nickel substrate is regarded as being superior to stainless steel in terms of performance.
