“…These three bands described above are also visible in the TiO 2 /CuS_15 spectrum. Furthermore, oscillation localized between 500-700 cm −1 are typical for Cu-S stretching and are only clearly visible in the CuS spectra [55,56]. In Figure 6d was shown the effect of TiO 2 modification using Bi 2 S 3 .…”

The effect of type (AgInS 2 , SnS, CuS 2 , Bi 2 S 3 ) and amount (5, 10, 15 wt%) of quantum dots (QDs) on the surface properties and photocatalytic activity of QDs-sensitized TiO 2 composite, was investigated. AgInS 2 , SnS, CuS 2 , Bi 2 S 3 QDs were obtained by hot-injection, sonochemical, microwave, and hot-injection method, respectively. To characterize of as-prepared samples high-resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-Vis spectroscopy and photoluminescence (PL) emission spectroscopy were applied. The size of AgInS 2 , SnS, CuS 2 , Bi 2 S 3 QDs were 12; 2-6; 2-3, and 1-2 nm, respectively. The QDs and QDs-sensitized TiO 2 composites obtained have been tested in toluene degradation under LEDs light irradiation (λ max = 415 nm and λ max = 375 nm). For pristine QDs the efficiency of toluene degradation increased in the order of AgInS 2 < Bi 2 S 3 < CuS < SnS under 375 nm and AgInS 2 < CuS < Bi 2 S 3 < SnS under 415 nm. In the presence of TiO 2 /SnS QDs_15% composite, 91% of toluene was degraded after 1 h of irradiation, and this efficiency was about 12 higher than that for pristine QDs under 375 nm. Generally, building the TiO 2 /AgInS 2 and TiO 2 /SnS exhibited higher photoactivity under 375 nm than the pristine TiO 2 and QDs which suggests a synergistic effect between QDs and TiO 2 matrix. Catalysts 2020, 10, 403 2 of 18 application of metal sulfides (M x S y ) for wide band semiconductors modification, because of their high charge separation efficiency and narrow band gaps, which possibly enable light harvesting at longer wavelengths [9]. Liu et al. studied the efficiency of AgInS 2 /TiO 2 heterostructures in 1,2-dichlorobenzene (o-DCB) degradation under visible light [10]. They observed that AgInS 2 /TiO 2 composites could expand the visible-light response range and greatly decreased the recombination of photogenerated electron−hole pairs in the composites. The degradation of o-DCB for the most active sample reaches about 50% after 8h of irradiation. Jang et al. prepared Ag-SnS-TiO 2 nanocomposite for methylene blue and rhodamine B degradation under simulated sunlight [11].The photoactivity of the produced photocatalysts was about 2-3 times higher than that of P25. Compared with bare TiO 2 the CuS/TiO 2 [12], CdS/TiO 2 [13-15], SnS/TiO 2 [16], Ag 2 S/TiO 2 [17,18], CuInS 2 /TiO 2 [19-21], Bi 2 S 3 /TiO 2 [22][23][24] nanocomposites present a significant improvement on photocatalytic reactions due to the decreasing recombination of electron-hole pairs and the broadened light absorption spectra. However, the metal sulfides commonly employed for TiO 2 modification have been used in nanoparticle sizes and not in quantum dots sizes. Further, it has been shown that the size of metal sulfides (MS) particles can have an impact on its physicochemical and optical properties. Recently, the literature data demonstrated that the decrease in particle size lowers the recombination of the electron-hole pair within the semiconductor particle. Quantum...

“…CuS nanoparticles were synthesized by chemical precipitation method and mixed with PVC in the presence of AP to develop the hybrid CuS-PVC membrane for detection of Cu (II). The as-synthesized CuS nanoparticles were granular and seen to be agglomerated with size distribution extending from 80 to 750 nm owing to the uncontrolled nucleation [61]. The electrochemical response of the fabricated CuS-PVC membrane was recorded and it was observed that the membrane would successfully detect Cu (II) as low as 64 ppb.…”

Development of rational synthesis methods for the hybrid metal chalcogenides is of great importance nowadays, due to their promising synergistic effect. The hybrid nanocomposites with well-defined nanostructures offers unique properties and fascinating applications. Recently, the CuS and its hybrid structures are largely adopted for the electrochemical sensor applications. In this review article, we have attempted to provide brief overview about synthesis and structural features of selected CuS and their composites. The review provide more detailed insights into their electrochemical sensor property with respect to selected biomolecule, such as glucose, tertazine, dopamine, hydrazine, Xanthine, and bisphenol A. In addition to the electrochemical sensing property of pure CuS, the importance of hybrid CuS with other nanomaterials, such as carbon fibers, and rGO, is also discussed in detail. Finally, this review provides summary and future scope of this work. This review would be very helpful for those who are working on copper sulfide based sensors to design their experiments and correlate their experimental results.

In this paper, various morphologies including spherical and flower‐like nanosheets‐based CuS were synthesized by the green hydrothermal synthesis method. Copper (II) nitrate trihydrate and thioacetamide (TAM) were selected as a Cu2+ and sulfur source, respectively. The effects of TAM/Cu molar ratio and reaction time on the phase and morphological evolution of the samples were studied. For this purpose, the samples were distinguished by FT‐IR, FE‐SEM, XRD, and ultraviolet‐visible spectroscopy. The photocatalytic and optical properties of the products were evaluated. It was found that self‐organized nanoflower(SONF) structures exhibit very good photocatalyst efficiency to degrade organic dye due to a significant increase in their surface area because of decorated nanosheets on the sample. Therefore, the SONF structures exhibited a very suitable potential as the photocatalyst agents.
