    摘要: Disclosed herein are a novel gemini surfactant and a method for preparing a mesoporous material using the gemini surfactant. The method for preparing a mesoporous material uses the novel gemini surfactant as a structure-directing agent to provide a mesoporous material has a pore size of 10 nm or less with uniform pore size distribution.
