超分子自组装化合物具有可调控的形貌和丰富的表面官能团.超分子或小分子单体之间的弱相互作用有利于除去模板,作为硬模板合成空心纳米结构(以Ti O2为例),不仅能得到具有可调控形貌的空心纳米结构,并且超分子模板可以回收和重复利用.实验表明,用三聚氰氨和三聚氰酸作为原料合成的超分子模板,有利于在模板表面复合无机组分,并且模板中的氢键在水中易断裂,因此可以通过透析方法除去模板得到空心纳米结构.这种超分子模板法也可以用于合成掺杂金属离子的空心结构纳米催化剂,进一步调控电子结构增加析氧反应的活性位点,降低超电势.更重要的是,此模板合成方法简单、耗能低、可重复利用,可以用于合成大批量的空心结构纳米催化剂.
Supramolecular self-assembly compounds have a controlled morphology and abundant surface functional groups.The weak interaction between supramolecular or small molecule monomers facilitates the removal of the template and the synthesis of hollow nanostructures (Ti O2 for example) as a hard template, Which can not only get hollow nanostructures with controlled morphologies, but also recover and recycle the supramolecular templates.Experiments show that the supramolecular templates synthesized with melamine and cyanuric acid are good for compounding on the template surface Inorganic components, and the hydrogen bonds in the template are easily broken in water so that the template can be removed by dialysis to obtain hollow nanostructures. This supramolecular template method can also be used to synthesize hollow structure nano-catalysts doped with metal ions and further regulate The electronic structure increases the active site of the oxygen evolution reaction and reduces the overpotential. More importantly, the synthesis method of the template is simple, low energy consumption and reusable, and can be used for synthesizing large quantities of nanostructured hollow-core catalysts.
