    Hydrothermal reactions of a hydrated sodium bismuth oxide, NaBiO3·1.4H2O were performed with transition-metal salts MCl2, M(NO3)2 and MSO4 (M: Co, Ni, Cu). The common identified products from nitrate and chloride solutions were (Bi,M)2O2(OH)NO3 and (Bi,M)OCl, respectively and every product contained a small amount of unknown impurity phases. Various unknown phases also appeared in the products from the sulfate solutions, and no common crystalline phases were observed. During the course of these hydrothermal reactions, a new bismuth sulfate, BiOHSO4 was found by using a H2SO4 solution, and its crystal structure was clarified by using single-crystal X-ray diffraction data. No photocatalytic activity for the phenol degradation of BiOHSO4 was observed under ultraviolet and visible light irradiation.
