COMPARATIVE PERFORMANCE ANALYSIS OF SOL–GEL METHOD AND HYDRO THERMAL METHOD FOR ZINC OXIDE NANOPARTICLE SYNTHESIS

Abstract

Nanomaterials have emerged as an amazing class of materials that consists of a broad spectrum of examples with at least one dimension in the range of 1 to 100 nm. Exceptionally high surface areas can be achieved through the rational design of nanomaterials. Nanomaterials can be produced with outstanding magnetic, electrical, optical, mechanical, and catalytic properties that are substantially different from their bulk counterparts. There has been considerable focus on the synthesis of metal nanoparticles with distinct and exceptional characteristics, making it a highly captivating area of research. Among these nanoparticles, Zinc Oxide NanoParticles (ZnO NPs) have gathered significant attention in the field of bioengineering. Various approaches have been explored for the preparation of ZnO nanoparticles. In this paper we are comparing two synthesis methods as Sol–Gel Method and Hydro Thermal Method for Zinc Oxide Nanoparticles. Sol-gel method based ZnO nanoparticles are compared with Hydrothermal based ZnO nanoparticles in terms of XRD, UV Visible Spectrum and SEM analysis. Sol-gel method based Al-doped Zinc Oxide Nanoparticle (AZnO) is compared with Hydrothermal based Al-doped Zinc Oxide Nanoparticle (AZnO) in terms of XRD, UV Visible Spectrum, SEM analysis and optical properties. At last Sol-gel method based Au-doped ZnO- Sm (NO3)3 is compared with Hydrothermal based Au-doped ZnO nanoparticles in terms of optical properties as transmittance and absorbance, structural properties as XRD analysis. From this paper we can conclude that, Sol-gel method based Au doped ZnO nano particles are efficient than Hydro thermal based ZnO nano particles.
