COMPARISON OF HEMATITE NANOCRYSTALLINE FILMS FOR USE IN PHOTOELECTROCHEMICAL CELLS

Abstract

Hematite, α-Fe2O3 nanocrystalline films have become a covetable material for use in photoelectrochemical cells because of efficient energy conversion in the visible electromagnetic spectrum and water splitting abilities to produce hydrogen gas. Nanoparticulate solutions of Fe2O3 were synthesized by a hydrolysis method with laboratory grade FeCl3 and with FeCl3 solution made from a sample of rust. The contaminated rust was collected from woven steel cable which was left exposed to harsh outdoor conditions. The solutions were deposited by a dip-coat method onto conductive glass and characterized by UV/ VIS, IR spectroscopy, and photoelectrochemistry. The efficiency of photocurrent production was evaluated
