| Popis: | Alginates are natural polysaccharides extracted mainly from brown algae, constituted by sequences of uronic units. These renewable biopolymers, available in virtually unlimited amounts, can be subjected to different manipulations rendering tailored gel materials endowed with excellent properties for catalytic applications. This chapter collects and summarizes emerging catalytic uses of alginate materials, in their different formulations, as: (i) supports for organometallic catalysts, (ii) supports for metal ions, (iii) supports for nanoparticles, and (iv) heterogeneous Bronsted acid promoters. A broad range of chemical transformations can be promoted by these alginate-based catalytic systems, which are tolerant to different reaction media. Some of the reported examples show the importance of morphology and textural properties of the alginate materials on the catalytic activity. Their heterogeneous nature guarantees the easy recovery from the reaction mixtures, and, in some cases, their reuse in several reaction cycles. |
