摘要

在这项工作中，通过在氯化钠存在的高压灭菌器中对三聚氰胺进行热处理，一步获得了基于三聚氰胺的超分子组装体。详细分析表明，所制得的粉末由两相组成：低结晶的Na-PHI薄片和棒状的melem水合物单晶（长几微米，宽~300 ~ 500 nm）。Melem水合物晶体吸收可见光范围内（Eg=2.7 eV）的光，在可见光下表现出空气对苯甲醇部分氧化制苯甲醛的光催化活性，对目标产物具有高选择性。在苯甲醇转化率为60%时，苯甲醛生成的选择性在95%以上。

One-Step Synthesis of Melem-Based Supramolecular Assemblies and Their Photocatalytic Properties

In this work, melem-based supramolecular assemblies were obtained in one step by thermal treatment of melamine in an autoclave in the presence of sodium chloride. The detailed analysis showed that the obtained powder consists of two phases: poorly crystalline Na-PHI flakes and rod-shaped melem hydrate single crystals (several micrometers long and ~300–500 nm wide). Melem hydrate crystals absorb light in the visible range (Eg=2.7 eV) and demonstrate photocatalytic activity in the reaction of partial oxidation of benzyl alcohol to benzaldehyde by air under visible light with high selectivity for the target product. At 60 % conversion of benzyl alcohol, the selectivity of benzaldehyde formation is above 95 %.
