Catalytic properties of metallosilicates

Metallosilicates with MFI structure containing metal atoms such as Ni, Co, Cu, Zn-Cu and Zn in framework have been synthesized with various metal/silicone (Me/Si) ratios (up to 0.1). The acidities of H-form metallosilicates were evaluated by some acid-catalyzed reactions (decomposition of 2-propanol, cracking of cumene and isomerization of 1-butene). The Zn-Si catalyst showed the highest acidities among various metallosilicates. In the metallosilicates-supported noble metal catalysts, 5%Pt/Zn-Si and 0.1%Pd/Cu-Si catalysts showed the highest activities for hydrodesulfurization of thiophene and hydrodechlorination of chlorobenzene, respectively.研究報
