Many thanks.the article is very close to my work.

Thomas Jüstel

Dear Ishray,

Most effective is the TiO2 polymorph anatas, which has an optical band gap of 3.5 eV. Thus you need UV-A radiation or higher energy.

Please have a look to the attached slide taken from one of my lectures.

All the best for your research!

Thomas

Thanks. I already used anatas titania but it didnot work effectively as antibacterial gel.

Best regards

Alan F Rawle

If you're starting with powdered TiO2 then you're going to have a dispersion issue, IMHO. Take a look at this webinar (registration required):
