Efficient nanophotocatalyt of hydrothermally synthesized Anatase TiO_2 nanoparticles from its analogue metal coordinated precursor

摘要

In this study, the hydrothermal synthesis of TiO_2 nanoparticles from its coordinated metal precursor via a novel modified hydrothermal method inside stainless steel autoclave has been reported. The synthesized nanoparticles were characterized via different techniques such as: XRD, XPS, TEM and SEM. The mechanism of formation has been proposed and this method is advantageous by producing pure anatase crystalline structure at mild conditions with a relatively high surface area of 208.7 m~2 g~(-1) and 19 nm in size. Finally we assessed its photocatalytic activity toward the photocatalytic degradation of methylene blue dye. The results revealed a photo-efficiency of 96 % with a degradation rate of 0.013 min~(-1).
