| 中文摘要: |
| 通过在化学还原过程中引入超声波制备了纯态NiB非晶态合金,并与同等条件下采用化学还原法制备的NiB非晶态合金进行比较.用XRD、ICP、TEM、SEM和SAXS等表征方法比较了样品的物性.以环丁烯砜加氢反应为探针考察了NiB非晶态合金催化剂的反应活性.结果表明,在化学还原法中引入超声波,生成的NiB非晶态合金的团簇更小,无序度更高,催化活性显著提高. |
| 英文摘要: |
| The amorphous NiB alloys were prepared by ultrasonic-chemical reduction and chemical reduction. The XRD, BET, ICP, TEM, SEM and SAXS were used to characterize the influence of ultrasonic on amorphous NiB alloys, and the hydrogenation of sulfolene to sulfolane was used to test the catalytic activity of samples. The results show that the particles sizes, diffusion and catalytic activity were improved by inducing ultrasonic to the chemical reduction. |
