RhCl₃ was heterogenized into renewable polysaccharide supports, and the effect of polysaccharide type on the new catalyst performances in a Suzuki cross-coupling reaction was studied. The conversion of the fresh iota carrageenan heterogeneous system (ἰ-RhCl₃), was found to be the highest, whereas it was lower than the conversion of its homogeneous analogue. In addition, the ἰ-RhCl3 (catalyst loading of 6.5 % wt) was proven to be efficient heterogeneous catalyst that was easily recycled, whereas the conversion was increased in the first and second cycles. Scanning electronic microscopy (SEM) combining Energy dispersive X-ray spectrometry and Surface analysis by X-ray photoelectron spectroscopy were performed, confirming that RhCl₃ was embedded within the ἰ-carrageenan. The Fourier-transform infrared spectrometry of the heterogeneous ἰ-RhCl₃ catalyst was compared to that of the native polysaccharide, and no new bands were detected. Nonetheless, a comparison of SEM image of ἰ-carrageenan with and without RhCl₃, as well as rheological measurements of the aqueous solution of ἰ with and without RhCl₃, indicated the incorporation of the polysaccharide with the RhCl₃.

RhCl ₃被异质化为可再生的多糖载体，并研究了多糖类型对铃木交叉偶联反应中新催化剂性能的影响。新鲜的iota卡拉胶非均相体系（ἰ-的RhCl的转化₃），被认为是最高的，而这是比其均相类似物的转化率更低。另外，证明了γ-RhCl3（6.5重量％的催化剂负载量）是有效的多相催化剂，其易于再循环，而在第一和第二循环中转化率增加。进行了结合能量色散X射线光谱法和X射线光电子能谱法的表面分析的扫描电子显微镜（SEM），确认了RhCl ₃被嵌入在角叉菜胶中。傅里叶变换异构ἰ-的RhCl的红外光谱₃进行比较，所述天然多糖的催化剂，并没有检测到新的谱带。尽管如此，ἰ角叉菜胶具有和不具有的RhCl的SEM图像的比较₃，以及具有和不具有的RhClἰ的水溶液的流变学测量₃，所示的多糖的结合与所述的RhCl ₃。
