In inorganic zeolite formation, a direct correspondence between liquid state species in the synthesis and the supramolecular decoration of the pores in the as-made final zeolite has never been reported. In this paper, a direct link between the sodium speciation in the synthesis mixture and the pore structure and content of the final zeolite is demonstrated in the example of hydroxysodalite. Super-ions with 4 sodium cations bound by mono- and bihydrated hydroxide are identified as structure-directing agents for the formation of this zeolite. This documentation of inorganic solution species acting as a templating agent in zeolite formation opens new horizons for zeolite synthesis by design.

具有水合氢氧根阴离子的钠阳离子超离子：沸石合成中的无机结构导向剂

在无机沸石的形成中，合成中的液态物质与制成的最终沸石中孔的超分子装饰之间的直接对应关系从未被报道过。在本文中，合成混合物中的钠形态与最终沸石的孔结构和含量之间存在直接联系，以羟基方钠石为例。具有 4 个钠阳离子的超离子被一水合和二水合氢氧化物结合，被确定为形成这种沸石的结构导向剂。无机溶液物种在沸石形成中充当模板剂的文档为通过设计合成沸石开辟了新的视野。
