Two new rubidium cerium (IV) iodates, namely RbCeI 5 O 15 and RbCeI 5 O 15 ⋅H 2 O, have been synthesized through hydrothermal reactions. Both compounds are composed of [CeO 8 ], [RbO 8 ] polyhedrons, and [IO 3 ] umbrella‐like groups, with RbCeI 5 O 15 ⋅H 2 O having an additional [H 2 O] group attached to the Ce atom. UV‐vis‐NIR diffuse reflectance spectrum indicates that the band gap of RbCeI 5 O 15 ⋅H 2 O is 2.76 eV. RbCeI 5 O 15 ⋅H 2 O shows high photocatalytic reactivity in the degradation of methyl orange (MO) under UV light irradiation.
