摘要：

Mesoporous channels (2.7 and 4.7 nm pore size) of FSM-16 were modified with titania or zirconia by the impregnation and hydrolysis of Ti or Zr alkoxides with subsequent calcination. Platinum carbonyl clusters [Pt-3(CO)(6)](n)(2-) (n = 4-6) were synthesized in the modified FSM-16 by the reaction of H2PtCl6 with CO and H2O at 323 K, and the clusters were characterized by IR and UV-Vis spectroscopies. Evacuation of the Pt carbonyl clusters at 573 K gave nanoparticles in FSM-16, and the resulting Pt/TiO2, (or ZrO2)/FSM-16 catalysts showed higher CO conversions and selectivities to C-2-C-3 alkanes in CO hydrogenation than the unmodified Pt/FSM-16.
