The catalyst was characterized by X-ray diffraction(XRD), scanning electron microscope(SEM), differential scanning calorimetry(DSC) and elecdes design suite(EDS) and was used for catalytic hydrogenation of 5-nitro-2-chloro-2', 4'-dimethylbenzenesulfonanilide (NCD). The amorphous alloy catalyst shows significantly high activity and selectively for hydrogenation of NCD to 5-Amino-2-chloro- 2', 4'-dimethyibenzenesuifonanilide (ACD).展开更多
