Inhibition of Corrosion on Mild Steel by Green Synthesized Titanium Dioxide Thin Film
J. Environ. Nanotechnol., Volume 14, No 3 (September 2025) pp. 76-80
Abstract
In this work, TiO2 nanoparticles were prepared from titanium tetra isopropoxide by conventional method and green synthesis using neem (Azadirachta indica) leaf extract. The green synthesized TiO2 was coated on mild steel plates. The morphological features of thin films were characterized by SEM and EDS. The rate of corrosion was assessed by weight loss and salt spray methods in NaCl environment.
