| Abstract: | Nano-sized platinum metal particles have been incorporated in mesoporous AlMCM-41 by g-radiolysis of the sample exchanged with [Pt(NH3)4]2+ ions. The sample has been characterized by a variety of techniques such as low angle X-ray diffraction, MAS NMR spectroscopy and transmission electron microscopy to establish the formation of both AlMCM-41 and nano-sized Pt metal particles. TEM shows a broad distribution in the size of Pt particles in the range of 10-20 nm. The catalytic activity of Pt/AlMCM-41 sample has been tested by room temperature hydrogenation of cyclohexene to form cyclohexane and temperature programmed hydrogen desorption studies. |
