Directed growth of 1D cadmium sulfide by chemically anchored Al2O3 and ZnO nanoparticles

Visible light assisted photocatalytic hydrogen generation and organic dye degradation by CdS–metal oxide hybrids in presence of graphene oxide

“…CdS/ZnO heterostructure was prepared by modified one pot hydrothermal method. 34 In a typical synthesis, ZnCl 2 (4 mmol) was dissolved in 20 mL water at 90 uC, followed by the addition 5 M NaOH solution dropwise with gentle stirring. When the pH of solution reached 7, a white precipitate of Zn(OH) 2 appeared.…”

“…CdS/Al 2 O 3 binary heterostructure was also synthesized by the single pot hydrothermal method. 34 In a typical synthesis, Al(NO 3 ) 3 ?9H 2 O (4.0 mmol) was dissolved in 20 mL distilled water followed by the addition of aqueous NH 3 (to maintain pH 7) and Cd(OOCCH 3 ) 2 ?2H 2 O (4.0 mmol) under vigorous stirring. After the addition of thioglycolic acid (4.0 mmol), the reaction mixture was stirred at room temperature for 30 min.…”

Micro Flowers of SrS/Bi2S3 Nanocomposite and Its Field Emission Properties

“…1.3 eV and ca. 4.0 eV, respectively [7,8]. The band gap value was calculated using the Kubelka-Munk function Eg = 1240/λ (where λ is the wavelength in nm) based on absorbance and was found to be two absorption steeps at ca.…”

Hierarchically Grown Urchinlike CdS@ZnO and CdS@Al2O3 Heteroarrays for Efficient Visible-Light-Driven Photocatalytic Hydrogen Generation

“…In a recent paper, our research group has demonstrated the synthesis of 1D CdS NWs on ZnO and Al 2 O 3 templates. 16 In essence, the surface area and band gap properties of the nanocomposites successfully induce their photocatalytic activity. Essentially, these nanostructured inorganic metal chalcogenideÀmetal oxide heteroarrays have unveiled exceptionally high rates of photocatalytic H 2 generation from water.…”
