Effect of Temperature on the Properties of Nickel Sulfide Films Performed by Spray Pyrolysis Technique

Abstract

In this work, we have prepared new materials of the nickel sulfide thin films by using the spray pyrolysis technique for promising co-catalyst to improve the photocatalytic performance or superconductivity. The effect of deposition temperature (523, 573 and 623 K) on structural, optical and electrical properties was investigated. The XRD diffraction shows that the prepared nickel sulfide at 523, 573 and 623 K having an orthorhombic, hexagonal and hexagonal structure, which were Ni3S2, Ni17S18 and NiS2, respectively. The minimum value of crystallite size (45,9 nm) was measured of deposited film at 573K. The thin films prepared at 523 and 573 K have an average transmittance is about 20 %. The prepared Ni1S2 thin film at T=623 K has the lowest calculated optical band gap and Urbach energy. The Ni1S2 thin film also has the best calculated of the refractive index and the extinction coefficient. The FTIR spectrums of the nickel sulfide have various bands such as Ni-S, C-H, O-H, N–H and C-S. The maximum electrical conductivity is 4,29x105 (Ω.cm)−1 was obtained at 573K of the Ni17S18. The nickel sulfide thin films sprayed at 573K have good structural, optical and electrical properties.

Study of the Structural, Optical, Electrical and Morphological Properties of Nickel Sulfide Thin Films Used in Supercapacitors

“…Thus, confirming the metallic behavior of the prepared NiS, which support the above claim about the Moss-Burstein effect. Also, these results are close to the reported data in the literature [26,27]. It is evident that the NiS prepared in this study is highly attractive as an electrode material for application in supercapacitors.…”

Exploring the Photocatalytic and Supercapacitive Potential of CuZr2S4 Thin Films: A Key to Cleaner and Safer Environments

“…These findings, derived from FTIR spectroscopy analysis, improve our understanding of the complex's chemical composition and provide insights into its unique bonding properties. Notably, the FTIR spectra at 1262 cm −1 displayed the occurrence of an amine functional group, which corresponds to the findings of Gahtar et al [ 30 ] Furthermore, a distinct CH 2 peak at 1490 cm −1 was observed, which is consistent with the findings of Mousavi‐Kamazani et al [ 31 ] Furthermore, Mousavi‐Kamazani et al [ 31 ] discovered an OH peak at 3445 cm −1 , which they attributed to absorbed atmospheric water. The detection of CH vibrations at 2960 cm −1 broadens our understanding of the complex diverse functional groupings, enriching its spectroscopic profile and allowing for a more in‐depth understanding of its chemical composition.…”

Transforming energy and water landscapes with MnS2:Ni9S8:Co3S4: A promising paradigm for a sustainable future

“…The presence of a carboxylic group was demonstrated by a prominent stretching peak at 1266 cm À1 , as previously reported by Chen et al [35] and Ghogare et al [36]. After conducting a thorough investigation, Gahtar et al [37] discovered the existence of an amine functional group at 1084 cm À1 . The existence of a CH 2 peak at 1511 cm À1 in the FTIR spectrum was another noteworthy discovery that was consistent with the research done by Mousavi-Kamazani et al [38].…”
