The construction and application of a new type of composite material are achieved more and more attention. However, expected SbSe/attapulgite composites aim to use the low price, and high adsorption of attapulgite in assembling SbSe is quite difficult to be acquired by a facile and benign environmental hydrothermal method. In this manuscript, we developed a new way for preparation of an emerging composite by means of SbO as a media linking SbSe and attapulgite together, and finally won an emerging composite SbSe/SbO@attapulgite, which presented an excellent catalytic properties for catalytic hydrogenation of p-nitrophenol. It was noted that the SbSe/SbO@attapulgite composites exhibited a high conversion rate for the hydrogenation of p-nitrophenol that was up to 90.7% within 15 min, which was far more than the 61.5% of SbSe sample. The excellent catalytic performance was attributed to the highly dispersion SbSe microbelts and SbSe@SbO@attapulgite rods, which would improve the adsorption of the reactant species and facility electronic transfer process of the catalytic hydrogenation of p-nitrophenol.
新型复合材料的构建和应用越来越受到关注。然而，预期的 SbSe/凹凸棒土复合材料旨在利用凹凸棒土价格低廉、吸附性能高的特点，但通过简单、良性的环境水热法来组装 SbSe 是相当困难的。在本手稿中，我们通过 SbO 作为连接 SbSe 和凹凸棒土的媒介，开发了一种制备新型复合材料的新方法，最终获得了一种新兴的复合材料 SbSe/SbO@attapulgite，该复合材料在催化对硝基苯酚的加氢反应中表现出优异的催化性能。值得注意的是，SbSe/SbO@attapulgite 复合材料在 15 分钟内对 p-硝基苯酚的加氢反应具有很高的转化率，达到 90.7%，远远高于 SbSe 样品的 61.5%。优异的催化性能归因于高度分散的 SbSe 微带和 SbSe@SbO@attapulgite 棒，这将提高反应物的吸附性和促进 p-硝基苯酚的催化加氢的电子转移过程。
