Unsupported Ni₃P-CePO₄ catalysts were prepared, characterized their catalytic performance in hydrodeoxygenation (HDO) was investigated using aqueous solution of phenol as the feed. The addition of CePO₄ resulted in enhanced HDO activity with the maximum activity at a Ce:Ni ratio of 3:10. The CePO₄ improved the dispersion of Ni₃P significantly and led to enhanced hydrogenation activity. CePO₄ provided dehydration sites as well through its surface acidity (mainly Lewis acid).
