Co-Mo-B amorphous catalysts with different Mo/Co molar ratios were prepared with chemical reduction method. Phenol, benzaldehyde and acetophenone were used as model compounds to test the catalyst hydrodeoxygenation activity. The catalyst surface composition had a great effect on catalyst activity. Both the conversion and the total deoxygenation rate could reach to 100%. The high catalytic activity of the Co-Mo-B amorphous catalyst depended on the sufficient supply of free hydrogen and the high content of Mo⁴⁺ Br?nsted acid on the catalyst surface.
