MANUFACTURING METHOD OF PHOTO-SENSITIZED MATERIAL USING SEAWATER ELECTROLYTE, THE PHOTO-SENSITIZED MATERIAL, PHOTOELTROCHEMICAL HYDROGEN PRODUCING APPARATUS AND CR(VI) REDUCTION DEVICE USING THE SAME MATERIAL

摘要

The present invention uses a natural seawater as an electrolyte to prepare a photosensitive material obtained by immobilizing crystalline titania on a titanium metal support by anodization. In addition, the photosensitive material is used as a photoanode to provide a photoelectrochemical hydrogen production apparatus having excellent hydrogen generation rate. In addition, the present invention provides a hexavalent chromium reduction apparatus using the photosensitive material as a photocatalyst, thereby reducing the hexavalent chromium, a representative toxic substance present in water, to trivalent chromium having relatively low toxicity by photochemical reaction. do.
