Improved Photocatalytic Activity of Dion-Jacobson-Type Tantalate Perovskites Modified with FeCl.

A rapid and feasible approach was used to develop visible-light-driven-type Dion-Jacobson perovskites by the modification of the RbLaTaO host (RbLTO) with FeCl through the molten salt route. X-ray diffraction (XRD) characterization showed that FeCl-modified layered perovskite (e.g.
