The principles and applications of semiconductor electrodes in photoelectrochemical cells (liquid junction photovoltaic, photoelectrosynthetic, and photocatalytic) are described. The extension of the principles of these cells to the design of simple particle systems for carrying out light-driven chemical reactions is discussed. [The SCI indicates that this paper has been cited in more than 245 ...

The application of sensitizers to utilize visible light for chemical reactions is an established method. Several recent publications have impressively demonstrated the versatile use of visible light for various transformations, such as the conversion of alcohols to alkyl halides, and [2+2], [3+2], and [4+2] cycloadditions as well as carbon– carbon and carbon–heteroatom bond formations. The comb...

This comparative study is about the heterogeneous photocatalytic degradation of two neonicotinoids, namely imidacloprid and thiacloprid, focusing on differences similarities in their transformation mineralization effect various additives, matrices, inorganic components. Besides dominant role • OH, which was confirmed by pH radical scavengers, direct charge transfer may also contribute to transf...

Heterogeneous photocatalysis was used for the degradation and mineralization of erythromycin (ERY), with a consequent production carboxylic acids. For that, series TiO2 Ti1-xSnxO2 structured catalysts, namely M1 to M5, prepared using washcoating method, catalytic coatings being deposited onto stainless steel meshes. Besides, activity systems compared that commercial mesh (CM). The results showe...

In the present study, calcination conditions during the synthesis of zinc oxide nanoparticles were optimized using response surface methodology (RSM) based on central composite design (CCD). After that, the effect of the type of UV irradiation on the photocatalysis of methylene blue (MB) dye was studied based on the kinetic model obtained at optimum conditions. Analysis of variance (ANOVA) exhi...

Photocatalysis induced by TiO2 and UV light constitutes a decontamination and antibacterial strategy utilized in many applications including self-cleaning environmental surfaces, water and air treatment. The present work reveals that antibacterial effects induced by photocatalysis can be maintained even after the cessation of UV irradiation. We show that resin-based composites containing 20% Ti...
