Herein, spherical-shaped ZnO nanoparticles of an average size of about 10 nm were successfully synthesized through a soft chem. approach. We further prepared the Ag/ZnO nanocrystals by varying the loaded amounts of metallic silver nanoparticles (1, 3, and 5 wt%) without using any reducing and stabilizing agent. X-ray diffraction (XRD) and XPS anal. confirmed the transformation of Ag ions into metallic Ag and the interaction between Ag and ZnO nanoparticles. High resolution-transmission electron microscopy (HR-TEM) images revealed that Ag nanoparticles of an average size of about 4.6 nm are present on the surface of spherical ZnO nanoparticles. UV-visible absorption spectra showed that the appropriate amount of Ag loading with ZnO shifted the band gap from UV to the visible region. Photoluminescence spectrum reveals the inclusion of Ag in ZnO and minimizes the recombination of electron-hole pairs. These synthesized Ag/ZnO nanocrystals were investigated for its potential applications in photocatalytic degradation of methylene blue dye under UV and sunlight irradiation and compared their efficiency with pure ZnO. Interestingly, it is seen that ZnO nanocrystals that are UV active become visible active when loaded with 1 and 5 wt% of metallic Ag. ZnO loaded with 1 wt% of metallic Ag completely degraded the methylene blue within 3 h under natural sunlight. Under UV light, 3 wt% of Ag in ZnO exhibits higher photocatalytic performance than the others. Thus, incorporating metallic Ag in ZnO nanoparticles shows excellent photocatalyst performance and recycling capability. Furthermore, the participation of different reactive species in the photocatalysis degradation mechanism was studied using four scavengers and the results indicate that superoxide and singlet oxygen are the dominant reactive species. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Related Products of 61-73-4).
3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Related Products of 61-73-4
