| Abstract: | Both unsupported NiB(P) and supported NiB(P) amorphous alloy catalysts NiB(P)/TiO 2 have been prepared by an induction chemical deposition method and electroless plating on powder, respectively. Their amorphous structures, properties and the interaction between the NiB(P) alloy and TiO 2 support have been characterized by XRD, ICP, SEM, TEM and DSC. Their catalytic activities have been measured during the hydrogenation of sulfolene. The stabilizing effect of the support on the NiB amorphous alloy observed by DSC and the superior hydrogenation activity of NiB/TiO 2 are attributed to the interaction between the NiB alloy and TiO 2 support, especially the high dispersion of NiB alloy particles on the support. |
