Exploitation of polymers as effective starting materials to produce various valuable catalysts is attracting the attention of industrial and academic researchers. Moreover, among all polymers, natural polysaccharides such as cellulose, starch, alginate, gum, pectin, chitin and chitosan have drawn the most attention in recent years due to their unique structural features and important potential applications. A lot of studies have been performed on the synthesis of polysaccharide based (nano)catalysts and their application in chemical transformations. The present review provides recent developments on polysaccharides as green resources for the production of (nano)catalysts. Herein, the application of polysaccharide based (nano)catalysts derived from different organisms, plants or animals in oxidative transformations has been reviewed. These compounds can be used as economical and recyclable catalytic materials for various oxidation reactions including oxidation of alcohols, phenols, sulfides etc. The challenges in the application of polysaccharide based (nano)catalysts have also been discussed.
将聚合物作为有效起始材料来生产各种有价值的催化剂的开发引起了工业界和学术界研究人员的关注。此外，在所有聚合物中，由于其独特的结构特征和重要的潜在应用，天然多糖如纤维素、淀粉、藻酸盐、树胶、果胶、甲壳素和壳聚糖近年来引起了最多的关注。人们对基于多糖的（纳米）催化剂的合成及其在化学转化中的应用进行了大量研究。本综述提供了将多糖作为生产（纳米）催化剂的绿色资源的最新进展。本文综述了不同生物体、植物或动物来源的多糖基（纳米）催化剂在氧化转化中的应用。这些化合物可用作经济且可回收的催化材料，用于各种氧化反应，包括醇、酚、硫化物等的氧化。还讨论了多糖基（纳米）催化剂应用中面临的挑战。
