The procedures for each impregnation were as follows. First, the precursor solution was prepared by dissolving a desired amount of Ni(NO3)2•6H2O or Co(NO3)2•6H2O in deionized water just sufficient to fill the pores of 3.0 g of SiO2 support. The precursor solution then was added to the support dropwise and treated with ultrasound for 1 h to facilitate metal dispersion. After aging in air at ambient temperature overnight, the catalyst was dried in air at 80 ¡ãC for 10 h and calcined at 450 ¡ãC for 3 h. The catalyst obtained after four times of impregnation was stored in vials and reduced under H2 flow with a flow rate of 60 mL/min at 450 ¡ãC for 3 h prior to catalytic evaluation.
