The diffusion of the precursor within the micellar structure is aided by interaction with the cationic head group of the surfactant leading to a unique method to facilitate the formation of highly disperse, uniform nanoparticles molded by the walls of the mesochannels. The nanoparticle incorporated mesoporous material has a highly enhanced surface area and adsorption capabilities in comparison to its parent materials without any pore blockage which makes this method ideal for the preparation of nanocatalysts.</p>1 aPrashar, Atul, K.1 aHodgkins, Robert, P.1 aKumar, Rajiv1 aDevi, Nandini  uhttp://library.ncl.res.in/content/situ-synthesis-pt-nanoparticles-sba-15-encapsulating-modified-template-micelles-size-0
