Abstract

Two types of materials in which the highest filled and lowest empty electron bands are mainly cationic have been investigated, namely, Bi/sub 4/Ti/sub 3/O/sub 12/ and Bi/sub 2/WO/sub 6/ with a filled Bi 6s band and empty Ti(W) 3d (5d) bands and NiNb/sub 2/O/sub 6/ and CoNb/sub 2/O/sub 6/ with filled narrow transition-metal bands and empty Nb 4d bands. Bi/sub 4/Ti/sub 3/O/sub 12/ shows peak photocurrents in a photoelectrochemical water decomposition cell, whereas Bi/sub 2/WO/sub 6/ does not. Also NiNb/sub 2/O/sub 6/ and CoNb/sub 2/O/sub 6/ behave differently. Whereas NiNb/sub 2/O/sub 6/ shows photocurrents, CoNb/sub 2/O/sub 6/ does not. These results are discussed in terms of bulk properties. The absence of a photocurrent is related to the formation of small polarons with high activation energy for migration. In agrement with this the compound Bi/sub 2/Wo/sub 6/ shows luminescence. 26 refs.
