Hierarchical porous materials have received a tremendous research interest because of their potential role in overcoming mass transport limitations of single-mode porous materials in various industrial applications. This work reports the synthesis of a novel hierarchical tri-modal porous silica using 7.5 molar ratio of 1,2,4-trimethylbenzene:tri-block copolymer, EO20PO70EO20. The pore size distribution curve shows the presence of three types of pores w h g d m ~8 25 d 89m. E m p m g h m h existence of macropores, larger ordered mesopores, and smaller ordered mesopores. This research provides new insights to develop novel tri-modal porous silica materials with versatile applications.
