摘要：

A facile route was developed to one-step synthesize ZSM-5 hollow microspheres. It was found that their crystallization occurred at near neutral pH with the assistance of EDTA2-ions via a "crystallization in a confined space" mechanism, and the resultant sample gave an exceptional yield of aromatics with a long catalytic lifetime in the methanol-to-aromatics process.
