On the growth and photocatalytic activity of the vertically aligned ZnO nanorods grafted by CdS shells

Increased photocatalytic activity of tube-brush-like ZnO nanostructures fabricated by using PVP nanofibers as templates

“…Zinc oxide (ZnO) is an excellent optoelectronic material because of its wide direct band gap (3.37 eV) and large exciton binding energy (60 meV) [9,10]. Among the reported semiconductor photocatalysts, ZnO attracts the most extensive interest because of its high stability, high photosensitivity, and strong oxidation activity, harmless and economical efficiency [11,12]. However, the small surface-area of ZnO powder limits its application.…”

Preparation of ZnO/CdS/BC Photocatalyst Hybrid Fiber and Research of Its Photocatalytic Properties

“…It can be overcome through the photocatalyst fixation instead of the recovery of the photocatalyst [10][11][12][13][14][15][16][17][18][19][20]. The key of immobilized technique is the performance of adopted immobilized carriers.…”

“…The combined ZnO and CdS system in nanosize area has attracted a great deal of attention in recent years. It can enhance the photocatalytic efficiency of ZnO under visible light and the service life of CdS, due to the fast separation of the photogenerated electron hole pairs [12][13][14][15][16][17].…”

“…a template in the synthesis of various inorganic nanostructures. Various methods have been reported for the synthesis of ZnO/CdS nanorods including colloidal chemical synthesis [16], electrochemical deposition [23], chemical bath deposition technique [24], facile chemical route [25], combined sol-gel/hydrothermal/SILAR method [26], chemical precipitation method [27], and sonochemical synthesis [28]. Among these methods, coprecipitation process is a simple and lowcost method that can be performed at low temperature and ambient pressure.…”

Visible Light Induced Innovative Technique for the Remediation of Wastewater containing Organic Contaminants using ZnO Nano Photocatalyst

“…ZnO nanostructure have high surface area are excellent material for various catalyst degradation and with this cause in mine we have chosen it for Acridine Orange (AO) dye degradation under visible light. Acridine orange (AO) is water soluble dye and used in colorization of textile, leather, paper and lacquer industries [8][9].…”
