摘　　要：ERB-1 zeolite emerges as a key bridging material for crafting heteroatom-containing MWW for versatile catalytic applications.In this study,we developed a solvent-free strategy facilitated by high-temperature condition and seed assistance,streamlining the synthesis of ERB-1 zeolite.This novel approach not only significantly reduces the growth time to 12 h compared to the conventional 168-h hydrothermal synthesis but also enhances product yield while minimizing waste generation.Benefiting from the platelet seeds and the grinding force,a distinct non-classical growth pathway,involving nanoparticle attachment,epitaxial growth,anisotropic assembly,and crystallization,was observed in the solvent-free synthesis.Through heteroatom substitution,pillared Sn-MWW was successfully prepared,exhibiting remarkable stability and catalytic performance in the Bayer-Villiger oxidation reaction of 2-adamantanone.Our findings present a simple and cost-effective way for rapid synthesis of MWW zeolite,with implications extending to diverse catalytic applications.
