The most important, from the point of view of the semiconductor photocatalysis, consequences of the transformation of the systems based on semiconductor microcrystals into the that based on the nanoparticles with quantum size effects have been analyzed. These are the expansion of the range of available photocatalytic reactions, growth of the efficiency of primary photochemical processes and the photocatalytic reaction as a whole, rise of the photocatalytic activity of narrow-band-gap semiconductors etc. The methods of the synthesis and stabilization of cadmium selenide nanoparticles and the CdSe-based composites in aqueous solutions have been developed. Spectral properties, such as light absorption, luminescence and Raman scattering, have been studied. Product Description popup.authors popup.nrat_date 2020-04-02 Close
