“…respectively, all deposited films have polycrystalline with the hexagonal phase also all diffraction peaks of CdS samples at different deposition time correspond to ( JCPDS no. 77-2306) this agreement with [15], it indicates that the very intense (002) plane with a preferential orientation (001) for all sample of wurtize CdS also two lattice constants a = 4.1409Å, c= 6.7198Å. The average crystal size (D) of CdS thin films about (22.25 nm) was derived from FWHM of peak corresponding to 2θ= 24.93 for sample that calculates using Scherer's equation [16]:…”

Studying the Effect of Deposition Time on Optical Properties of CdS Thin Films R. A. Al-WardyDepartment of clinical laboratory science/college of pharmacy/Al-mustansiriyah university e-mail: dr.rusuladnan@uomustansiriyah.edu.iq Abstract. We have studied in this work the effect of deposition time on the absorption spectra and the optical energy gap of CdS thin film. That prepared by chemical bath deposition method (CBD) on glass substrate at temperature of (80 ± 5)°C. The structural features were examined by X-ray diffraction (XRD) is wurtzite structure for all samples. Transmittance spectra have been recorded in order to determine absorbance, reflectivity, absorption coefficient and the optical constants such as refractive index, extinction coefficient, real and imaginary part of dielectric constant. It was seen that all the parameters under investigation affected by deposition time (1,2 3, and 4) hours.

“…CdS NRs with a high aspect ratio showed higher photocatalytic activity due to the restrained electrons in a specific direction that influences the electronic and optical properties of the photocatalyst [33]. Liu et al found the improved CdS photocatalytic performance due to the increase of exposed 002 facets [34].…”

Visible Light-Driven Photocatalytic Rhodamine B Degradation Using CdS Nanorods

2021

In this work, highly crystalline CdS nanorods (NRs) were successfully synthesized by a facile, one-step solvothermal method. The as-prepared CdS NRs powder was characterized by XRD, FESEM, Raman, PL, XPS, BET, and UV-visible techniques to evaluate the structural, morphological, and optical properties. The photocatalytic performance of the as-synthesized CdS NRs was investigated for the photodegradation of RhB dye under visible light irradiations. It has been found that CdS NRs show maximum RhB degradation efficiency of 88.4% in 120 min. The excellent photodegradation ability of the CdS NRs can be attributed to their rod-like structure together with their large surface area and surface state. The kinetic study indicated that the photodegradation process was best described by the pseudo-first-order kinetic model. The possible mechanism for the photodegradation of RhB dye over CdS NRs was proposed in this paper.

“…Among them, sulfide semiconductors (such as CdS, MoS 2 , Ag 2 S, etc) have drawn much attention due to their narrow bandgaps which are responsive to visible light . For example, CdS with narrow bandgap (∼2.4 eV) has been well developed for visible‐light‐driven photocatalysis, including nanorods, nanoflowers, nanotubes and so on. In addition, MoS 2 nanomaterials (nanosheets, nanoparticles, nanotubes, etc) can also be used as effective photocatalysts, due to wide‐spectrum response, large specific surface area and quantum confinement effects .…”

The development of effective, visible‐light‐drivable and reusable photocatalysts has drawn great attention for purifying the flowing wastewater. Herein, we have designed and prepared MoS2/CdS heterostructures on carbon fiber (CF) cloth as a novel filter‐membrane‐shaped photocatalyst. With CF cloth as the substrate, the growth of MoS2 nanosheets (thickness: ∼20 nm) and CdS nanoparticles (∼5 nm) have been achieved by using a hydrothermal‐chemical bath deposition two‐step route. CF/MoS2/CdS cloth shows a strong and wide photoabsorption accompanied by a small peak with an edge around 700 nm. Under visible‐light irradiation, CF/MoS2/CdS cloth (area: 4×4 cm2) can expeditiously remove 97.3 % rhodamine B, 55.6 % tetracycline hydrochloride and 68.4 % hexavalent chromium after 100 min, and 97.3 % methylene blue after 70 min. In particular, when CF/MoS2/CdS cloth (diameter: ∼10 cm) is used as a filter‐membrane to photocatalytically degrade the flowing wastewater (10 mg L−1 RhB, rate: ∼1 L h−1), 92.6 % RhB can be eliminated in eight grading pools. Therefore, CF/MoS2/CdS cloth has the capacity to be a recyclable photocatalyst with high efficiency for purifying the flowing wastewater.
