摘要：

Ni-Mo-B amorphous catalysts promoted by Co and La were prepared by chemical reduction of the corresponding metal salts with sodium borohydride. The effects of additives for the catalytic activity were studied using the hydrodeoxygenation of phenol as model reaction. Co- and La-promoted Ni-Mo-B amorphous catalysts exhibited higher catalytic activity. The total selectivity of oxygen-free products was increased to 93.1% with a selectivity of 3.2% aromatics on Co-Ni-Mo-B and the total H/C atomic ratio in the products was improved to 1.99 on La-Ni-Mo-B.
