“…Heterostructures consisting of a semiconductor (CdS), conducting organic polymers, and various types of sensitizers that had proved much more effective catalysts than cadmium sulfide for the release of hydrogen during the action of visible light were constructed for the first time [13,17,19]. Photocatalytic processes for the production of hydrogen involving metal sulfide microhetero transitions [8,10,12,16,19], photocatalysts based on mesoporous titanium dioxide [20,21,24,25,27], nanostructured semiconductors, etc. [14,15,18,19,22,23,26,28] were also investigated.…”
