Synthesis and characterization of nanostructured photocatalysts based on the nitrogen- and sulfur-doped titania for the water pollutants degradation under visible light

Abstract

A nonmetal-doped titania has attracted considerable attention in recent years due to its photocatalytic activity in the visible part of the solar spectrum, which is beneficial with regards to pure TiO2. Among the explored nonmetal dopants, nitrogen and sulfur have been shown to be the most promising for the enhancement of photocatalytic activity of TiO2 under visible light. These nonmetals can be introduced to the TiO2 lattice by employing various precursors and preparation methods...

Dopiranjem titan(IV)-oksida nemetalima omogućuje se fotokatalitiĉka aktivnost pod dejstvom vidljive svetlosti, što predstavlja veliku prednost dopiranog u odnosu na ĉist TiO2. Najznaĉajniji nemetalni dopanti su azot i sumpor, koji se mogu inkorporirati u strukturu TiO2 primenom razliĉitih prekursora i postupaka sinteze...
