Deep and detailed discussions on chemistry, chemical physics, photoelectrochemistry, photophysics, photocatalysis and possible applications of nanostructured semiconductor materials have shown increasing interest in the matter by scientists representing various research areas as well as industrial enterprises. Indeed, solar energy conversion and chemical methods for its realization became very popular again after the a great jumpa of renewable energy sources between the middle of the 1970s and the beginning of the 1980s. Several excellent books have been published over the past years,...
