Bi4TaO8Cl and Bi4TaO8Cl:Gd3+ photocatalysts were synthesized by the solvothermal technique. The phase, microstructure, optical properties, and photocatalytic activities were investigated. Both Bi4TaO8Cl and Bi4TaO8Cl:Gd3+ have the singly orthorhombic phase and the flower‐like hierarchical structure....
