How to control the size distribution and morphology of amorphous alloy is of vital importance in improving their catalytic performance. In this work, uniform and ultrafine NiB amorphous alloy catalysts were prepared by using a hydrogelator, 2,4-(3,4-dichlorobenzylidene)-d-sorbitol, as growth controller as well as PEG800 and tannin for co-additives, which exhibit excellent performance toward the selective hydrogenation of cinnamic acid into hydrocinnamic acid. TEM images indicated the addition of PEG800 and tannin affected the self-assembly of gelator from large aggregates into small assemblies and then affected the morphology of NiB catalysts, leading to enhancement of catalytic activity and stability.

如何控制非晶态合金的尺寸分布和形态对提高其催化性能至关重要。在这项工作中，均匀的和超细型NiB非晶态合金通过使用水凝胶，2,4-（3,4-二氯苯）中制备的催化剂- d -山梨醇，生长控制器以及PEG800和鞣酸用于共添加剂，其显示出在将肉桂酸选择性氢化为氢肉桂酸方面表现出优异的性能。TEM图像表明，PEG800和单宁的添加影响了胶凝剂从大聚集体到小组件的自组装，进而影响了NiB催化剂的形态，从而提高了催化活性和稳定性。
