A tungsten-molybdenum solid solution oxide ((Mo_0.5, W_0.5)O₃) powder hybridized with Cu(Mo_0.5, W_0.5)O₄ was prepared using impregnation method and mechanochemical processing. The powder prepared through the impregnation method exhibited antibacterial effects both in the dark and under visible light. The contribution of MoO₃ in the powder surface was inferred for activity in the dark. The phase transition temperature of (Mo_0.5, W_0.5)O₃ was decreased more than 50°C by planetary ball milling. The powder produced through mechanochemical processing also exhibited photocatalytic decomposition activity on the gaseous 2-propanol under visible light.
