Surface modification of ZnO and Ti02 nanoparticles under mild hydrothermal conditions

Abstract

There are various techniques for synthesizing different Nanoparticles depending upon the desired properties, application, etc. One of these widely applied techniques is Hydrothermal. However, this technique is known for bulky materials and fabrication of nano-scale materials requires adopting some strategies to alter the properties of materials synthesized. We developed surface modification for this drawback. Application of surface modifier, or surfactant, or capping agent, or organic ligands in proper concentration could not only change morphology, reduce particle size, but also change the surface chemistry of the nanoparticles fabricated. The ZnO and TiO2 nanoparticles were modified using n-butylamine and caprylic acid as surface modifier under mild hydrothermal conditions (p= autogenous, T= 150-250°C, and t= 18 h). The nanoparticles modified were systematically characterized using Powder XRD, FTIR, SEM, zeta potential, and BET surface area. The characterization results revealed that nanoparticles have small size range, low agglomeration and highly stable.
