We report a simple method to control phase formation in manganese sulfides during hydrothermal synthesis from aqueous solutions of manganese nitrate and thioacetamide without any additives or surfactants. In this work, MnS2, MnS or MnS2/MnS composites were obtained by adjusting the proportion of thioacetamide in the initial precursor mixture. The photocatalytic activities evaluated by H2 generation under ultraviolet light showed that MnS phase was found to be more active than the MnS2.
