Effect of calcination temperature on the growth of TiO_2 nanoparticle prepared via sol-gel method using triton X-100 as surfactant

摘要

In this paper we investigated the synthesis and characterization of surfactant-interceded TiO_2 that were used as adsorbents and photocatalysts. Non-ionic surfactant (Triton X-100), were used to obtain the separation and monodispersion in the reaction solution. The surfactant affects the packing density (crystallite aggregation) during deposition improved the photodegradation efficiency. We prepared TiO_2 nanoparticles through sol-gel method using ethanol and methanol as a mix solvent, surfactant (Triton X-100) and titanium tetra-isopropoxide precursor at a room temperature. And the present work provides a basic understanding of the effect of surfactant and temperature on the growth of TiO_2. The as prepared TiO_2 were calcined at 300°C, 400°C, 500°C and 600°C temperatures. The nanostructure and morphology of as prepared nanoparticles were investigated by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM).
