A nano‐crystalline In 2 O 3 was synthesized using calcinations methods and was used as a photocatalyst to degrade sulfan blue (SB) dye. In addition, this study addresses the conditions of the degradation and the factors that influenced the catalysis. In 2 O 3 was prepared by calcining In(OH) 3 at heat ranges of 100–700 °C for 24 h. The In 2 O 3 was characterized using field emission scanning electron microscopy (FE‐SEM), an X‐ray diffractometer (XRD), thermogravimetric analysis (TGA), and high‐resolution X‐ray photoelectron spectroscopy (HR‐XPS). The activities of these samples were tested for the photocatalytic degradation of SB dye. The results indicated that the In(OH) 3 that was calcined at 300 °C for 24 h had the best performance.
