Amorphous Ni-B catalyst has excellent catalytic hydrogenation performance, but the poor stability limits its application. A Ni-B/ K2Ti6O13amorphous catalyst, prepared by impregnation of K2Ti6O13 support with Ni ions which were reduced by KBH4 aqueous solution, was employed in liquid-phase hydrogenation of nitrobenzene to aniline. The obtained catalysts were characterized by the X-ray diffraction (XRD), thermogravimetric analysis(TG), temperature programmed reduction (TPR), and their specific surfaces were determined by N2 BET method. The results show that, the appropriate loading of Ni could stabilize the Ni-B active species of the catalyst. Meanwhile, it could also increase the thermal stability and activity of the catalyst. The optimal catalyst loading is 30 %, theoretically, with the reaction temperature of 100 ℃, hydrogen pressure of 2.0 MPa and reaction time of 120 min, the conversion of nitrobenzene and selectivity of aniline reached 99.5% and 99.9% respectively. The reaction conversion and selectivity was 98% and 93% after 6 times used , respectively.
