ZnAl水滑石负载钯催募化剂的制备及催募化干用

  A series of hydrotalcite-supported palladium catalysts (Pd/ZnAl-LDH) were prepared with the ion exchange-reduction method,and characterized with XRD,TEM and ICP. Further,their catalytic performance for benzyl alcohol oxidation in low toxicity solvents (ethanol and water) were investigated. Solvent properties,Pd loading,O2 pressure and reaction time had great influences on the prepared catalysts. Pd/ZnAl-LDH catalyst with 2% Pd loading exhibited optimum catalytic performance in ethanol solvent,and its activity and selectivity to benzaldehyde could reach 93.6% and 93.3%, respectively.
