style=\"color:red\">芳香</span>胺类化合物及其衍生物是一类重要的有机合成中间体,广泛应用于染料、农药、医药及其他精细化学品.目前催化<span style=\"color:red\">芳香</span>硝基化合物还原制备<span style=\"color:red\">芳香</span>胺的多相催化体系多使用含有d6-d10贵金属以及高活性Ni的催化剂.为了提高反应的选择<span style=\"color:red\">性</span>,金属纳米颗粒的尺寸控制、合金效应、金属载体强相互作用、溶剂以及添加剂的筛选等不同手段被采用.考虑到该类催化剂复杂的制备方法以及易氧化的性质,近年来稳定高效的非贵金属体系的开发得到了广泛关注.MoS2是一类重要的高温加氢催化剂,不饱和的Mo位点(CUS Mo)被认为在催化过程中起到了关键<span style=\"color:red\">性</span>作用.但是理论与实践已经证明,作为代表<span style=\"color:red\">性</span>的二维材料,MoS2的活性位点多集中于层状结构的边楞结构处.占有最大暴露面积的基面结构因为稳定的Mo-S化学键组成在化学反应中多表现为催化惰性.通过剥离的手段可以有效提升活性位点的数目,但新增的活性位点仍然多集中于层状结构的边楞结构处而不是基面.在MoS2与MoO2结构中Mo-S和Mo-O的键长不同,同时S和O的配位形式也不同.可以预见的是,如果MoS2结构中的一部分S元素被O元素取代,在这样的材料中将会出现大量缺陷以及活性CUS Mo结构.结合先前关于硫化钼材料的制备方法,我们通过部分硫化还原[Mo7O24]6-前驱物的方法制备了氧掺杂的MoS2材料(标记为O-MoS2).通过XRD,XPS,Raman和EDX等表征发现,不同的Mo-O结构存在于O-MoS2材料中.HRTEM表征结果显示,O-MoS2表面存在着丰富的结构缺陷.EXAFS结果显示,O-MoS2材料中可能含有四配位以及五配位的CUS Mo结构.以甲酸铵还原硝基苯为探针反应检测了CUS Mo结构.发现O-MoS2可以在水相条件下高效催化<span style=\"color:red\">芳香</span>硝基化合物还原生成相应的<span style=\"color:red\">芳香</span>胺,且催化剂稳定,可以多次循环使用.结合对照不同催化剂的NH3-TPD数据以及MoS2结构模型,我们发现O-MoS2材料中含有丰富的CUS Mo结构,这些CUS Mo结构更多地存在于材料的基面而非边楞结构.我们认为,对于该类掺杂MoS2材料的制备及结构表征将有利于拓宽MoS2催化剂从高温气相反应到温和液相反应中的应用.","authors":[{"authorName":"张超锋","id":"12cb6af5-30e0-472f-88c2-0521ddc60295","originalAuthorName":"张超锋"},{"authorName":"王旭","id":"3fc7f1c6-0069-4d45-a397-41760a8e26a5","originalAuthorName":"王旭"},{"authorName":"李名润","id":"e2200b8d-6ad5-4d3e-8be6-7c08fcac0d29","originalAuthorName":"李名润"},{"authorName":"张志鑫","id":"394391b7-a1d2-4745-842a-244b03b74190","originalAuthorName":"张志鑫"},{"authorName":"王业红","id":"82e76167-fd2d-4210-8e62-e444f60a2a46","originalAuthorName":"王业红"},{"authorName":"司锐","id":"b7a50432-2189-43d9-bb96-cd789a2034c0","originalAuthorName":"司锐"},{"authorName":"王峰","id":"71c0da64-4027-4343-ad9e-5ff01c1bc43a","originalAuthorName":"王峰"}],"doi":"10.1016/S1872-2067(16)62504-4","fpage":"1569","id":"73ad1301-92b4-4668-ac5e-69b9bf76bac3","issue":"9","journal":{"abbrevTitle":"CHXB","coverImgSrc":"journal/img/cover/CHXB.jpg","id":"18","issnPpub":"0253-9837","publisherId":"CHXB","title":"催化学报
