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.
