Clarifying the locations of precious metals in sol gel derived nano-TiO2

Autor: K.E. Rammutla, S.L.P. Savin, Rudolph M. Erasmus

Publikováno v: Materials Today: Proceedings. 3:1460-1469

Titania is a cheap and nontoxic polymorphic material of current interest for a variety of technological applications. Generally, TiO 2 , with a band gap of 3.2 eV, can only be excited by a small UV fraction of solar light, which accounts for only 3-5
