Preparation of visible light sensitive nano-sized N-TiO2 photocatalysts and their photocatalytic activity under visible light

This study aimed to develop a photocatalyst that responds to visible light. For the preparation of visible light sensitive photocatalysts, N was doped into TiO2(N-TiO2). To inhibit the recombination of excited electrons and holes, transition metals (M = Pt, Cu, Fe, Cr) were loaded on the N-TiO2. N-TiO2 nanotubes were also synthesized by a hydrothermal treatment of the prepared N-TiO2 in a strong basic environment.

Study on 2- Diazo-4,6-dinitrophenol in waste water using UV-H2O2/TiO2

This article focuses on researching the possibility of applying Nano TiO2 photocatalyst in an advanced UV-H2O2 oxidation process to decompose 2- Diazo-4,6-dinitrophenol (DDNP) in wastewater of propellant and explosives production facilities. Effects of reaction time (0-120 minutes), pH, UV light, molar ratio of H2O2/TiO2, reaction temperature and initial DDNP concentration on DDNP treatment efficiency were evaluated.
