Photocatalytic property of colloidal TiO2 nanoparticles prepared by sparking process

Titanium oxide nanoparticles (NPs) were successfully prepared by sparking off two titanium tips into water for 1-5 h. The nanoparticle-dispersed water was obtained for further characterization. The transmission electron microscopy result shows that the particle size is in the range of 1-5 nm. The el...
