Abstract

Photophysical and photocatalytic properties of molybdates and tungstates with a scheelite structure were investigated. The band gaps of scheelite compounds narrowed when the compounds were composed of Ag + and Bi 3+ ions. (NaBi) 0.5MoO 4 (BG: 3.1 eV) and (AgBi) 0.5MoO 4 (BG: 3.0 eV) showed the photocatalytic activities for O 2 evolution from an aqueous solution containing an electron acceptor. On the other hand, (NaBi) 0.5WO 4 (BG: 3.5 eV) produced H 2 from an aqueous solution containing an electron donor.
