Abstract

Semiconductor heterostructures NT-TiO2/CdSe have been obtained by supporting semiconductor films CdSe on a Ti-substrate with the generated layer of nanotubes TiО2 by potentiostatic anodic polarisation. Photoelectrochemical processes on polycrystalline NT-TiO2/CdSe-photoelectrodes have been studied. The reasons of increase in efficiency of phototransformation after inoculation of a surface of photoelectrodes by Pt and Zn nanoparticles have been analyzed. It has been shown that nanostructurization of electrodes leads to increase in their photosensitivity what is connected with decrease in surface recombination speed. Overall efficiency of photoanodes studied in a photoelectrochemical cell with hydrogen accumulation has been examined.
