Drawing on independent work carried out by academic and industrial researchers using the immobilized TEMPO catalyst SiliaCat TEMPO, in this study we show how shifting the carboxylation process mediated by TEMPO in solution to a process mediated by the above-mentioned hybrid sol-gel catalyst allows the synthesis of insoluble polysaccharide nanofibers of superior quality, eliminating waste. This will dramatically reduce the polysaccharide nanofiber production costs opening the route to large-scale production and uptake of these versatile nanofibers in a variety of functional products where their use has been limited by high cost. The results of this study will be useful for catalysis and biotechnology researchers as well as for chemistry educators teaching green chemistry, nanochemistry, and catalysis using the outcomes of recent research.
本研究利用学术和工业研究人员使用固定化 TEMPO 催化剂 SiliaCat TEMPO 进行的独立工作，展示了如何将 TEMPO 介导的溶液中的羧化过程转变为上述混合溶胶-凝胶催化剂介导的过程，从而可以合成质量更优的不溶性多糖纳米纤维，同时消除浪费。这将极大地降低多糖纳米纤维的生产成本，为大规模生产这些多功能纳米纤维开辟道路，并将其应用于各种功能产品，此前由于成本高昂，这些纳米纤维的应用受到限制。这项研究的结果将对催化和生物技术研究人员以及教授绿色化学、纳米化学和使用最近研究成果的催化的化学教育工作者有用。
