Abstract ordered mesoporous materials have tunable pore sizes between 2 and 50 nm and are characterizedby ordered pore structures and high surface areas this makes them particularly favorable for a number of applications such as catalysis the architecture of mesoporous solid has seen many innovations based on template mechanism among them,SBA-type materials has thicker walls,more silanol groups, large pore sizes, large pore volumes, high thermal and hydrothermal stability. these advantages generated variety of applications,and alot of interest .the purepose of the present study is to further developing method of direct incorporatien of aluminum into sba-15 framework in acid mediate synthesis and to characterize theri structres,and acid nature. |
