The invention belongs to the technical field of molecular sieves, and relates to a silicon-germanium UTL macroporous molecular sieve and a preparation method thereof. In the preparation method, 7-azaspiro-[6, 6]-tridecane molecules are used as an organic template agent for preparation. Compared with an existing template agent, the template agent used in the patent is simple in structure, the synthesis process is simple and easy to operate, and complex synthesis processes and purification steps are not needed; hydroxyl is adopted to replace F <-> to serve as a mineralizer in synthesis of the UTL molecular sieve, and the silicon-germanium UTL molecular sieve which is intact in crystallization and unique in morphology can be obtained without adding fluoride. The synthesis formula range of the UTL type molecular sieve synthesized by adopting the template agent is wide, no obvious competitive phase appears, and pure UTL molecular sieve crystals are relatively easy to obtain. 本发明属于分子筛技术领域，涉及一种硅锗UTL大孔分子筛及其制备方法。所述制备方
