Preparation characterization and photocatalytic activity of polycrystalline ZnO/TiO2 systems.2. Surface, bulk characterization ad 4-nitrophenol photodegradation in liquid-solid regime
Article Abstract:
Characterization of mixed ZnO/TiO2 polycrystalline solids were prepared by different methods like electron spin resonance spectroscopy (ESR), Fourier transform infrared spectroscopy (FTIR) and monitoring of pyridine (py) and boric acid trimethyl ester (BATE) adsorption for determining surface acidity and basicity. The photoreactivity behavior of many samples mainly reflects on two bare ZnO samples, depending on the amount of zinc and a formation of ZnO layer on the particles surface.

Preparation characterization and photocatalytic activity of polycrystalline ZnO/TiO2 systems. 1. Surface and bulk characterization
Article Abstract:
Polycrystalline ZnO/TiO2 solids are prepared with four different methods using home prepared TiO2 (anatase) or TiO2 (rutile) as supports and Zn(NO3)(sub 2).6H2O as precursors for ZnO. Results indicated that no solid-state reactions occurred when relatively low temperature of calcinations was used.

Preparation, characterization, and photoactivity of polycrystalline nanostructured TiO(sub 2) catalysts
Article Abstract:
Selected samples were classified by X-ray diffractometry, distinct surface area, porosity determinations, scanning and transmission electron microscopy. The samples obtained from TiCl(sub 4) were the most photo-active and neither filtration nor calcification was required.
