%X 纳米GeO<sub>2</sub>是用于光学性能优异、耐老化性能好的高品质聚酯生产的主要催化材料，目前该催化材料的制备研究在国内鲜有报道，国内聚酯企业大都通过从国外进口纳米GeO<sub>2</sub>材料以满足生产需求，这较大地限制了国内高端聚酯产业的发展。本文讨论了聚酯合成的催化机理及发展现状，介绍了纳米GeO<sub>2</sub>用于聚酯催化的优势，分析了已有纳米GeO<sub>2</sub>材料的制备方法、研究现状、难点及挑战，提出了低成本制备纳米GeO<sub>2</sub>材料的可行性方案及最新进展。本文为低成本制备纳米GeO<sub>2</sub>催化材料提供了新的思路，对于促进我国高品质聚酯工业生产的发展具有积极意义。<br />
Nano-GeO<sub>2</sub> particles are a major catalyst material for synthesizing high-quality polyesters with excellent optical and aging-resistant performance. Nowadays, there are few reports for its prepa-ration research in China. Domestic enterprises have to import nano-GeO<sub>2</sub> powders to meet their production demands. Therefore, the development of inland high-quality polyesters is restricted. In this work, we discussed the catalytic mechanism of polyester synthesis and its current situation, and introduced the advantages of nano-GeO<sub>2</sub> served as catalyst. Then, we came up with the appli-cable preparation method of low-cost nano-GeO<sub>2</sub> and the latest research advance based on analyzing the previous synthesis methods, research status and fabrication difficulties of nano-GeO<sub>2</sub>. This paper provides a new idea for the production of low-cost nano-GeO<sub>2</sub> catalysts, and may leave a positive impact on the development of domestic high-quality polyesters.
