含有各种取代基的芳香硝基化合物选择加氢制备相应的芳胺是精细化工领域最重要的反应之一,在农药、医药、染料及高分子聚合物等领域具有广泛的应用.但是传统的过渡金属纳米催化剂由于活性金属尺寸分布不均一,往往导致目的产物选择性低.

生物柴油按制备方法可分为三代.第一代生物柴油以油脂为原料,通过酯交换反应将油脂转化为脂肪酸甲酯(FAME);第二代生物柴油通过加氢反应将油脂转化为异构烷烃类液体燃料;第三代生物柴油由生物质气化生成合成气,再经过费托合成和加氢异构化反应,生成异构烷烃.本文介绍了课题组针对三代生物柴油生产,开发新催化过程,研究相关反应机理和催化剂构效关系的工作.
单层或者多层原子厚度的二维材料由于其特殊的形貌、相对低的原子配位数从而表现出不同于传统纳米材料的性质,其中最典型的例子就是石墨烯.但是除此之外,对于金属单质在原子级别的二维纳米结构调控的报道还比较少,因为这类材料通常不稳定,容易团聚成纳米块状结构.
