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 BiOl. 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.
