Photocatalytic Degradation of Organics by Using Nanocrystalline Titania

الملخص EN

Titanium dioxide nanoparticles were prepared by a modified sol-gel route.

Titanium butoxide was used as precursor and nebulizer was used for a fine spray of particles.

The prepared powders were characterized by FT-IR, SEM, XRD, and TGA-DTA methods.

The results indicated that nanoparticles with small size and high surface area were synthesized.

XRD result indicated that TiO2 nanoparticles were obtained in pure anatase crystalline form with a crystallite size of 40 nm.

The catalytic activity of as-synthesized nanoparticles was tested for the degradation of formic acid and toluene.
