“…Với cấu trúc nano, pha tạp và composite, hiệu quả quang xúc tác của ZnO đã được tăng lên đáng kể [5,6]. Nguyên nhân là làm giảm được khả năng tái tổ hợp của các cặp electron-lỗ trống trong quá trình quang hoá, đồng thời đã mở rộng được bờ hấp thụ của vật liệu về vùng khả kiến [5][6][7]. Tuy nhiên, hầu hết các nghiên cứu hiện nay đang tập trung vào loại vật liệu nano dạng bột mà chưa có nhiều nghiên cứu về màng nano ZnO cho ứng dụng quang xúc tác [8][9][10][11].…”

In this study, zinc oxide (ZnO) doped with Sn thin films were deposited on the glass substrate at 550 °C by dip-coating technique using the solution synthesized by sol-gel method. The structural, surface morphology, optical and photocatalytic property of thin films were studied. X-ray diffraction (XRD) analysis showed that the Sn-doping greatly changed the microstructure, morphology and optical properties of ZnO films, which may contribute to the enhancement of photocatalytic activity. Additionally, the photocatalytic activity was investigated using methylene blue dye under solar irradiation, with has high UV index from 7 to 8. The results indicated that Sn-doped ZnO had a higher photocatalytic activity and Sn dopant greatly increased the photocatalytic activity of ZnO thin film.

“…Recently, the application of zinc oxide(ZnO) has increased significantly because of its special properties .ZnO nanoparticles exhibit unique properties such as large surface relative to total volume,biocompatibility,nontoxicity,chemical and photochemicalstability, electrochemical activity, optical transparency, high electron communication features, optical, biologicaland electrical, long-term environmental stability [1][2][3][4]. ZnO nanostructure has been widely used in areas as varied as tissue, organic coatingsor antibacterial activity due to the non-toxic nature of zinc oxide and its ability to block ultraviolet rays [6], in addition to its use in other fields.…”

Hydrothermal technology has many advantages compared to other growth methods such as the availability of their simple equipment,catalyst-free growth,Environmental friendliness, less dangerous environmental, and low costs. Combine spinning method technology with Hydrothermal could improve the structural of ZnO NS by increasing the formation of ZnO NS due to influence of heat annealed treatments on the structure of ZnO NS. ZnONano-Sheets (NS)were prepared to employ hydrothermal process utilizing zinc acetate, that has the chemical composition (Zn (CH3CO2)2.2H2O),as a precursor. After preparing the material, it is deposited in two methods, the first being distillation of the material on the glass (S1),while the second method was using the spinning technique (S2).The spinning method showed better results than the other method.The synthesized ZnO NS were analyzed byscanning electron microscopy (SEM),X-ray diffraction (XRD) analysis and their optical properties have been characterized utilizingUV- absorption spectra.

Nanomaterial is a rapidly growing area that is used to create a variety of new materials and nanotechnology applications from medical, pharmaceuticals, chemical, mechanical, electronics and several environmental industries including physical, chemical and biological nanoparticles are very important in our daily life. Nanoparticles with leaf extract from the healthy plant are important in the area of research using biosynthesis methods. Because of it’s used as an environmentally ecofriendly, other than traditional physical and chemical strategies. In particular, biologically synthesized nanoparticles have become a key branch of nanotechnology. The present work presents a synthesis of zinc oxide nanoparticles using an extract from the Argemone leaf Mexicana. Biosynthetic nanoparticles are characterized by X-ray diffraction (XRD), Ultraviolet visible (UV-vis) spectroscopy analysis, a Fourier Transform Infrared Spectroscopy analysis (FTIR) and a scanning electron microcopy (SEM), X-ray analysis with dispersive energy (EDAX). XRD is used to examine the crystalline size of zinc oxide nanoparticles. The FTIR test consists in providing evidence of the presence of targeted teams. UV is used for optical properties and calculates the energy of the bandwidth slot. The scanning microscope emission reveals the morphology of the surface and the energy dispersive X-ray analysis confirms the basic composition of zinc oxide nanoparticles. It is found that zinc nanoparticles are capable of achieving high anti-fungal efficacy and therefore have a high potential antimicrobial activity of ZnO NPs, like antibacterial and high antioxidant. Zinc Oxide nanoparticles from the Argemone Mexicana leaf extract have several antimicrobial applications, such as medical specialty, cosmetics, food, biotechnology, nano medicine and drug delivery system. ZnO nanoparticles are important because they provide many practical applications in industry. The most important use of nanoparticles of ZnO would be strong antibacterial and antioxidant activity with a simple and efficient biosynthesis method may be used for future work applications.
