In this work, highly crystalline and uniform (Bi19S27I3)0.6667 nanorods were firstly synthesized by a one-step hydrothermal process. The formation of the (Bi19S27I3)0.6667 nanorods consists of nucleation and crystal growth in agglomerates of spherical particles. The obtained (Bi19S27I3)0.6667 nanorods with a narrow band gap of about 1.80 eV, a wide visible light absorption spectrum, and a more negative conduction band potential are capable of producing high-reducibility electrons, and an efficiently photogenerated carriers separation capability. The results demonstrate that the (Bi19S27I3)0.6667 nanorods can be as efficient and stable photocatalysts for Cr(VI) photoreduction and RhB degradation reactions. The photocatalytic reduction efficiency of Cr(VI) over the (Bi19S27I3)0.6667 nanorods was determined to be more than 3 times those of the corresponding BiOI and Bi2S3 photocatalysts under visible light. The detailed formation mechanism of (Bi19S27I3)0.6667 nanorods and the reaction mechanism of Cr(VI) photoreduction were proposed based on various characterizations.
