The synthesis, characterization, and catalytic performance of the new sulfonic acid supported on the magnetic nanoparticles with maghemite coating were reported. The morphology, particle size, structure, magnetic properties, and the formation of nanoparticles with narrow size distribution were investigated. Chemical analysis was performed by using TEM, wide‐angle XRD, FTIR spectroscopy, and X‐ray fluorescence
报道了在具有磁赤铁矿涂层的磁性纳米粒子上负载的新型磺酸的合成,表征和催化性能。研究了形态,粒径,结构,磁性能以及窄尺寸分布的纳米粒子的形成。化学分析是通过使用TEM,广角XRD,FTIR光谱和X射线荧光进行的,磁性测量是通过振动样品的磁力分析法进行的。发现该催化剂对吡咯的合成具有活性。这些颗粒的纳米尺寸范围由于可用于反应的表面积增加而促进了催化过程。
