Abstract:

Several ironIII tungstates have been prepared, and their crystallographic, magnetic, electric and photoelectronic properties have been characterized. The compounds crystallize with the tri-alpha-PbO2 structure, and the actual ordering of the MO6 octahedra MFe or W appears to determine these properties. Under illumination, Fe2WO6 photoanodes show an intermediate photoresponse between conducting alpha-Fe2O3 and WO3, although the flat-band potential is still too positive. Author
