摘要：

BiOI microspheres were synthesized via a facile hydrolytic method with sodium dodecyl sulfate (SDS). The results showed that 8% SDS-BiOI microspheres possessed the homogeneous morphology, larger specific surface area and more oxygen vacancies compared with the pure BiOI. Moreover, the adsorption efficiency of rhodamine B (RhB) and methyl orange (MO) for 8% SDS-BiOI reached almost 96.4% and 79.4%, respectively. It was found that the oxygen vacancy induced by SDS improved adsorption performance of BiOI due to the enhanced electrostatic interaction.
