This book was released on 2012-06 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consists of synthesis and characterization of ZnO and Mn-doped ZnO nanoparticles for photocatalyst process. The work contains synthesis (co- precipitation), Characterization (TEM, SEM, EDX, FTIR, XRD, BET, UV-visible NIR) and application of ZnO and Mn-doped ZnO nanoparticles. The application included photodegradation of m-, o- and p-cresol that was carried out under UV and visible irradiation at room temperature, atmospheric pressure, and different PH by batch photoreactors. The intermediates were identified by UPLC and mineralization was confirmed by TOC measurement. As a result, 1%wt Mn-doped ZnO with lower particles size, higher surface area, high cresols adsorption, lower agglomerate, appropriate band gap and higher photodegradation ability than other % of Mn-doped ZnO is the best photocatalyst that may enhance the photocatalyst activity of ZnO under visible light.

Download or read book Hydrothermal Growth of Zinc Oxide Nanorods Doped with Manganese written by Rajni Bagga and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: ZnO nanostructures can be grown using a variety of techniques. Using a hydrothermal method, ZnO nanostructures can be produced easily on a large scale due to the low temperature involved. ZnO is a well-studied wide-band gap (3.37 eV) n-type semiconductor material with significant properties such as a large exciton binding energy (60 meV). In this project we have chosen the hydrothermal method to synthesize undoped and manganese doped zinc oxide nanorods at different growth temperatures of {60}^0C, {70}^0C, {80}^0C, and\ {90}^0C respectively for 20h. We made a seed layer of ZnO on the Si substrate by annealing zinc acetate at {400}^0 C. The morphology of the nanorods was visualised by taking their side and top SEM images. Micro Raman Spectra shows the crystal orientation of the nanorods with respect to substrate and optical Raman-active modes of undoped and doped nanorods. Room-temperature micro-Photoluminescence spectra of nanorods shows the sharp near band emission at 383 nm and broadband defect emission in the visible range. From EPR spectroscopy we find out whether a significant amount of Mn was incorporated into nanorods. Our findings indicate that the presence of Mn in the growth medium results in improved morphology, even though at the lowest growth temperatures there is no clear incorporation of Mn into the nanorods. This implies that the presence of the Mn ions in the group medium is enough to increase the growth rates of ZnO, regardless of whether the ions are incorporated into the crystal or not.

Download or read book Transition Metal Doped Zinc Oxide as Diluted Magnetic Semiconductor written by Zheng Zuo and published by . This book was released on 2013 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal doped ZnO has been proposed to be a Diluted Magnetic Semiconductor with room temperature ferromagnetism. High quality Mn doped ZnO was grown on R-sapphire substrate. Results support intrinsic ferromagnetism, while [Mu]B/ion number was found to be larger than maximum permitted by Hund's law. Saturation strength and coercivity field was found to be manipulated by varying Mn doping concentration. Mn/Ag co-doping was found to alter saturation strength and coercivity field as well. Ag was investigated as substitution dopant to achieve high quality p-type ZnO. With optimization of growth parameters, phase segregation was suppressed and p-type was observed. Besides being p-type, Ag doped ZnO was found to exhibit room temperature ferromagnetism. This is the first high quality demonstration of Ag doped ZnO as DMS.
