of the silver nanoparticles (Ag NPs) onto the material. The silver nanoparticle was decorated over the HMP‐2 to prepare the corresponding catalyst (Ag‐HMP‐2). The characterization of the newly produced material has been conducted by N2 adsorption/desorption studies, XPS, FE‐SEM, transmission electron microscopy (TEM) and Powder X‐ray diffraction (PXRD) methods. This microporous catalyst has spectacular
超交联微孔聚合物(HMP-2)量身定制合成的最新进展凭借其可调节的孔隙率,可操作的设计和绝对有序的结构而聚集了相当多的浓度。这种结构完美的Ag NPs负载的碳催化剂(Ag-HMP-2)是通过无水氯化铁(III)催化的4,4'-双(溴甲基)-1,1'-联苯和咔唑之间的Friedel-Crafts烷基化反应合成的通过将银纳米颗粒(Ag NPs)附着到材料上。将银纳米颗粒装饰在HMP-2上以制备相应的催化剂(Ag-HMP-2)。新生产的材料的表征已由N 2进行吸附/解吸研究,XPS,FE-SEM,透射电子显微镜(TEM)和粉末X射线衍射(PXRD)方法。该微孔催化剂在大气二氧化碳压力下于60°C下具有各种活性,可用于从各种类型的炔丙基胺衍生物生产四酸。在末端炔烃上进行平行固定CO 2的尝试,以在1个大气压下合成丙酸。催化剂(Ag-HMP-2)表现出足够的循环能力,可在不降低催化活性的情况下最多进行五次催化运行,生成四酸和丙酸。
