1. Photocatalytic TiO2 thin films for air cleaning : Effect of facet orientation, chemical functionalization, and reaction conditions
Abstract : Poor indoor air quality is a source of adverse health effects. TiO2 coatings deposited on well-illuminated surfaces, such as window panes, can be used to fully mineralize indoor air pollutants by photocatalysis. READ MORE

2. Water film-mediated mineralogical transformations and photocatalytic reactions
Abstract : Mineral particles capture water vapor in the atmosphere in the form of water films that are only few monolayers thick. Water films form nanoscale hydration environments that mediate a wide range of important reactions in nature and technology. READ MORE

3. MECHANISMS OF ENHANCED ACTIVITY OF MODEL TiO2/CARBON and TiO2/METAL NANOCOMPOSITE PHOTOCATALYSTS
Abstract : TiO2 is the most widely used photocatalyst for energy and environmental applications because of its outstanding physical and chemical properties. However, the quantum efficiency of TiO2 is greatly diminished by fast electron-hole pairs recombination and light absorption only in the UV region. READ MORE

4. Sol-gel Synthesis and Photocatalytic Characterization of Immobilized TiO2 Films
Abstract : Contamination of surface and ground water from industrial wastes and anthropogenic activities represents one of the greatest challenges to the sustainable development of human society. Heterogeneous photocatalysis, a kind of advanced oxidation process characterized by the production of highly oxidative hydroxyl radicals, is a relatively novel subject with tremendous potential in water treatment applications.
