摘　　要：纳米超细分子筛的制备是纳米材料研究领域的热点之一。对纳米超细分子筛的两种合成方法——控制晶化条件法(包括溶胶的控制晶化合成和凝胶的控制水热晶化合成)和微反应器模板内限制晶化法的研究和发展现状进行了评述,并分别阐述了各自的优缺点,提出了今后研究的重点。微反应器模板内限制晶化法由于优点突出,将成为纳米超细分子筛合成的重要路线。The preparation of the nano - sized superfine molecular sieve was one of the hot spots in the research field of nano - materials. This paper commented on the research and current developing situation of the two synthesis methods for nano - sized superfine molecular sieve - the method of synthesis by controlling crystallizing conditions （ including the synthesis method of sol by controlling crystallization and the synthesis method of gel by controlling hydrothermal crystallization） and the method of synthesis by limiting crystallization in the template microreactor. The advantages and disadvantages of these methods were discussed respectively. The focal point for the future research was also put forward. Due to the outstanding advantages of the method of sytbesis by limiting crystallization in the template microreactor, it will become the major route for synthesizing nano - sized superfine molecular sieve.
