PMOs with diverse mesostructures, morphologies and compositions have emerged in the past few years, and shown unprecedented properties. Recent years have seen the great progress in the controlled synthesis of functionalized PMOs towards specific application demands, particularly in catalysis. This Feature Article describes selected examples of the synthesis of functionalized PMOs for catalytic applications in the past few years. 大伙有空的话也欢迎指导一下俺的拙作，呵呵！很有幸，就在大师发表的文章的前面一篇。 J. Mater. Chem., 2009, 19, 1937–1944 Mesoporous transition metal oxides: characterization and applications in heterogeneous catalysis This highlight article is devoted to catalytic applications of mesoporous materials containing transition metal oxides (Ti, Nb and Ta). In general, these mesoporous molecular sieves (MMS) can be readily modified by doping with other elements, reduction or acid treatment to extend their applications in catalysis. We highlight some of the recent findings from our group focusing on the modification of existing mesoporous transition metal oxides, characterization of these new mesoporous structures and their respective surface properties, and the exploration of their potential catalytic applications in areas such as dinitrogen activation, benzylation, alkylation, and isomerization. Confinement effects and porosity are also discussed, which are known to strongly affect diffusion and catalytic properties, resulting in the existence of an optimal catalytic efficiency depending on pore size and internal surface area. http://rapidshare.com/files/2299 ... _1937_1944.pdf.html http://www.namipan.com/d/J.%20Ma ... d7d1aad550533620700 [ Last edited by nxl5096224 on 2009-12-24 at 12:45 ] |
