Bi 2 WO 6 ordered porous film with open pores , an example of a photocatalytically active ternary metal oxide under visible‐light irradiation, is prepared using a simple and reproducible route. The ordered porous Bi 2 WO 6 films exhibited much higher photocatalytic activity and photocurrent coversion efficiency than nonporous Bi 2 WO 6 films under visible‐light irradiation ( λ > 420 nm).
