The invention discloses a method for preparing arene from methyl alcohol based on a catalytic effect of a zeolite molecular sieve with a porous structure. The method comprises the following steps: firstly, preparing a polystyrene microsphere and controlling the diameter of the polystyrene microsphere within 50-700nm by adjusting a preparation condition; taking the polystyrene microsphere as a template and tetrapropylammonium hydroxide as a template agent and adopting a one-step crystallization method for preparing the zeolite molecular sieve with the porous structure; lastly, taking the prepared zeolite molecular sieve with the porous structure as a catalyst and the methyl alcohol as a raw material and preparing the arene. The catalyst adopted by the method is high in catalytic effect, the prepared product is high in arene content and the target product is excellent in selectivity. 本发明公开了种基于多孔结构沸石分子筛催化的甲醇制备芳烃的方法，包括以下步骤：首先本发明制备聚苯乙烯微球，并调节制备条件来控制聚苯乙烯微球的直径的大小为50-700nm，然后以聚苯乙烯微球为模板，以四丙基氢氧化铵为模板剂，采用步晶化法制得了多孔结构沸石分子筛；
