The photocatalytic methods for nitrogen oxides removal were recently very intense areas of scientific research. Photo-deNO x processes offer interesting ways for abatement of these harmful gases. This review describes several methods for removing NO by photocatalytic reactions. These methods can be classified into three major groups: photo selective catalytic reduction (photo-SCR), photo-oxidation...
Unlike the profound knowledge of the reaction mechanisms occurring in water phase photocatalysis, still fairly little is known on the reaction mechanisms occurring on the catalyst surface when dealing with gaseous pollutants. Unfortunately, there are some differences between both reactions. For one, there are no abundant hydroxyl radicals present in the gas phase, so that possibly other species prove...
The interactions of human and bovine serum albumins (HSA and BSA) with various drugs and nanomaterials receive great attention in the recent years owing to their significant impact in the biomedical field. Although there are various techniques available for studying such interactions, fluorescence spectroscopy is the most appealing one due to its high sensitivity and straightforwardness. Detailed...
A critical overview is presented on the role that first row p-block elements boron, carbon, nitrogen and fluorine, employed as dopants of TiO 2 , have in improving the capability of this photocatalyst in harvesting solar light for photocatalytic applications. The peculiar physicochemical properties of doped TiO 2 materials are described in terms of the results of both theoretical calculations...
Measurement and evaluation methods for the performance of dye-sensitized solar cells (DSCs), of which the mechanism for photocurrent generation is quite different from that of silicon-type solar cells, are reviewed here and a relevant method proposed. The slow response times and nonlinearity of DSC photocurrents against the light intensity (irradiance) at wavelengths of incident light are profoundly...
