Electrodeposition, which features low cost, easy scale-up, good control in the composition and great flexible substrate compatibility, is a favorable technique for producing thin films. This paper reviews the use of the electrodeposition technique for the fabrication of several representative chalcogenides that have been widely used in photovoltaic devices. The review focuses on narrating the mechanisms for the formation of films and the key factors that affect the morphology, composition, crystal structure and electric and photovoltaic properties of the films. The review ends with a remark section addressing some of the key issues in the electrodeposition method towards creating high quality chalcogenide films.

“…The reduction of Pb ions generally leads to a positive charge in the solution, resulting in a neutral lead atom on the cathode. As will be shown later, the higher the concentration of Pb ions, the greater the number of adatoms removed and the more they eventually form a lattice [13].…”

“…Maintaining a constant temperature will ensure homogeneous dissolution across the total anode area during the anodization process. Abhijit Ray [13], however, reported that high temperatures speed up the chemical dissolution process. Consequently, working temperatures should usually be kept fairly low(~ambiant) so that the oxide does not dissolve completely.…”

In this study, the electrodeposition technique has been used to deposit low concentrations of highly toxic lead (Pb) cations into a solution of nitrate at a constant potential of -1V on fluorinedoped tin oxide electrodes (FTO). Monitoring of the reaction was conducted with the assistance of a computerized potentiostat/galvanostat setup, in cyclic voltammetry and in situ chronoamperometry modes. X-ray diffraction, scanning electron microscopy, energy dispersive X-Ray, and ultraviolet-visible spectroscopy techniques were used to examine the crystal structure, morphology, and optical properties of the lead deposits, respectively. Pb regular micro-hexagons have been identified; their size and density were significantly influenced by the cationic precursor's concentration. The correlation between the morphological and crystallographical structures of the electrodeposits was discussed. Based on chronoamperometric measurements, a mechanism for the growth of Pb deposits on FTO substrate has been proposed.Based on the reported results, electrodeposition processes of low heavy metals concentrations in contaminated water could be optimized using the eco-friendly electrodeposition technique.

Graphene oxide/Au nanoparticles: Synthesis, properties, and application: A mini‐review

There has been rapid growth in research activities on the potential of graphene oxide/Au (GO:Au) composite for different applications. The GO:Au composite has been widely explored in applications such as biomedicine, electrochemical biosensors, optical limiters, and organic dye degradation. The increased interest in GO:Au for these applications is the consequence of harvesting the electronic bonding structure that is due to the formation of sp 3 C C clusters from defected sp 2 C═C and attachment of Au atoms onto the C═C carbon matrix.The defection of the sp 2 cluster of GO can be achieved by the method of improved synthesis and functionalization with Au surfactants. The current review explores an overview of the different synthesis techniques for producing GO:Au composites, which is an important factor in controlling the particle and size distribution of the composites. The electronic, electrical, and magnetic properties of GO:Au composites are covered as it relates to photochemical, memristive, and biomedical imaging applications. The low coercivity and remanence are consistent with superparamagnetic behavior. Although, GO:Aunanocomposite (NC) are widely explored for biomedicine and drug delivery applications, future applications of the composite can be useful for magnetic resonance imaging owing to the superparamagnetic behavior. The future possibilities of GO:Au-NP are promising in the field of bioimaging and electronic devices. The electrical property of GO:Au-NC can be fused with its electrochemical property for supercapacitor applications. In some cases, GO:Au-NC is used as an anchor material with conducting polymers to enhance the supercapacitor properties. Furthermore, the synthesis of mono-disperse few-layer graphene is still challenging owing to economic cost and the graphite exfoliation process. The review of GO:Au composite from a material physics perspective aims to elucidate the current trends as well the future possibilities offered by the composite for various promising applications. Novelty Statement• This review focused on the graphene oxide-gold nanocomposite which is an outstanding composite material for different applications.
