Abstract: A supported Fe-Ni bimetallic catalyst is prepared through KBH4 reduction method and is applied to hydrogenation of phenol.The as-synthesized catalysts are characterized by means of inductively coupled plasma mass spectrometry,X-ray diffraction,X-ray photoelectron spectroscopy and transmission electron microscopy.The effects of reaction temperature and pressure on the hydrogenation performance of phenol are investigated over the as-prepared catalyst with different atomic ration of Fe/Ni and the stability of the catalyst is evaluated too.It is shown that when the atomic ratio of Ni precursor and Fe precursor reaches 2:1,the as-synthesized catalyst shows the best catalyst performance.Both the conversion of phenol and the selectivity of cyclohexanol can reach 99.9% at 120℃,3.5 MPa.The catalyst remains basically initial activity after being used 5 times.
