Some of the Study of the Physical Properties of the Membranes Binary Tin Oxide Sno2 Pure and Tinged with Nickel Ni at Different Rates Distortion

Some of the physical properties were studied, which included the optical properties of the films of pure tin dioxide doped with nickel in proportions (1,5,7%) at a molar concentration of 0.1moL/L, which were prepared by thermal chemical deposition method on glass bases at a temperature of (400ºC). The study included the optical properties through the transmittance spectrum (T) of the films of pure tin dioxide doped with banned nickel in the range of wavelengths (300-900). It was noticed that the transmittance of pure tin dioxide films is high, ranging between (82-76) % approximately in the visible region, as we have noticed that by using doping, the permeability of oxide films decreases in succession, and the reflectivity increases with the increase in the percentage of doping gradually and that the refractive index increases with the increase in the energy of the photon. The rest of the optical constants were calculated as functions of the photon's energy that smells (refractive index).

The Sono-Photocatalytic Performance of PAN/g-C3N4/CdS Nanofibers Heterojunction

The Polyacrylonitrile (PAN)/g-C3N4/CdS nanofiber sono-photocatalysts were successfully synthesized by an ordinary electrospining-chemical deposition method. The PAN/g-C3N4/CdS heterojunction nanofibers constructed with the CdS nanoparticles deposited on the PAN/g-C3N4 nanofibers. The g-C3N4/CdS heterojunction increase of light absorption and the construction of heterojunction can depress recombination of charge carrier and PAN nanofibers improve the recyclability successfully. Finally, a highly effective photocatalytic activity was performed by degradation of Rhodamine B (RhB) in visible light irradiation. Furthermore, an ultrasonic method is introduced into the sono-photocatalytic system to enhance the degradation efficiency of RhB ascribed to the synergistic effect of ultrasound.

Preparation of Hollow SiO2@BiOI Nanocomposites and Their Photocatalytic Performance in Ammonia Nitrogen Degradation

Hollow SiO2 microsphere-supported bismuth oxyiodide (BiOI) nanocomposites were prepared using Bi(NO3)3 · 5H2O and KI as the precursors of BiOI at 80 °C in an aqueous solution by the liquid chemical deposition method. The BiOI nanosheets with the thicknesses of 25–40 nm and the widths of 1–2 μm were deposited on the hollow SiO2 microsphere surfaces. There were interactions between the BiOI nanosheets and hollow SiO2 microspheres, which enlarged the ban gap of the BiOI nanosheet as compared with the pure BiOI. The band gap energy increased with the increase in SiO2/BiOI weight ratios. The hollow SiO2@BiOI nanocomposites showed high photocatalytic activity in ammonia nitrogen degradation when the photocatalytic degradation reaction was performed in aqueous solution under visible light irradiation. The degradation extent of ammonia nitrogen was upto 81% when the ammonia nitrogen degradation reaction was photocatalyzed by the hollow SiO2@BiOI(100:10) nanocomposite at an initial concentration of ammonia nitrogen of 10 mg L−1 and 25 °C for 4 h. The reaction kinetics of ammonia nitrogen degradation was well simulated by the first-order reaction model.

Fabrication of a superhydrophobic surface by a template-assisted chemical deposition method

A novel chemical deposition method was developed to fabricate an appealing micro-nanostructure on an iron sheet with the assistance of a candle soot coating that served as the surface template. The process is only three steps. First, a soot coating was deposited on a iron sheet surface by placing the iron sheet over the flame of a burned candle. Secondly, the iron sheet was immersed in a copper dichloride ethanol solution for 0.5 hours to obtain a copper layer with a rough three-level structure consisted of microprotrusions, submicron-scale papillae and nanosheets. Thirdly, the prepared iron sheet was modified with octadecanoic acid. It was indicated that the resulting rough copper surface on the iron sheet had great superhydrophobicity whose water contact and sliding angles reach 156.9° and 4.6°, respectively. Here, a new approach may be developed for design and fabrication of ideal hierarchical surface structures via chemical deposition.

Highly Efficient Photocatalysis by Zinc Oxide-Reduced Graphene Oxide (ZnO-rGO) Composite Synthesized via One-Pot Room-Temperature Chemical Deposition Method

We synthesized zinc oxide-reduced graphene oxide (ZnO-rGO) composites using a one-pot chemical deposition method at room temperature. Zinc powder and graphene oxide (GO) of different mass ratios (1 : 1, 1 : 2, 1 : 5, 1 : 10, and 1 : 20 GO to Zn) were used as precursors in a mildly alkaline solution. UV-Vis spectroscopy was used to study the photocatalytic efficiency of the samples through the photodegradation of methylene blue (MB). UV-Vis measurements show the fast decomposition of methylene blue under UV light illumination with the best degradation efficiency of 97.7% within one hour, achieved with sample ZG2 (1 GO : 2 Zn mass ratio). The corresponding degradation rate was kZG2 = 0.1253 min−1, which is at least 5.5 times better than other existing works using hydrothermal methods. We argue that the excellent photodegradation of MB by ZG2 is due to the efficient charge separation brought about by the electronic interaction of the rGO with the ZnO and the formation of a Zn-O-C bond, as supported by XRD and Raman spectroscopy measurements.
