Single-layered, double-layered, and triple-layered Pt nanoparticles with a well-defined arrangement were encapsulated inside metal–organic frameworks (MOFs) to investigate the catalytic performance influenced by the progressive increasing of Pt nanoparticles inside MOFs; the results show that the catalytic activity of the Pt–MOF hybrid catalysts increases progressively with the progressive increasing of the Pt nanoparticles inside MOFs. Progressive increasing of Pt nanoparticles with a multiple-layered manner inside MOFs provides a new route for designing well-organized hybrid catalysts of noble metal nanoparticles and MOFs with enhanced catalytic activity.

金属有机骨架内部具有多层方式的Pt纳米颗粒的逐步增加，以增强催化活性。

将具有明确排列的单层，双层和三层Pt纳米颗粒封装在金属有机框架（MOF）内，以研究受MOF内部Pt纳米颗粒的逐渐增加影响的催化性能。结果表明，Pt-MOF杂化催化剂的催化活性随着MOF内部Pt纳米颗粒的逐渐增加而逐渐增加。在MOF内部以多层方式逐渐增加Pt纳米颗粒为设计组织良好的贵金属纳米颗粒和具有增强催化活性的MOF杂化催化剂提供了一条新途径。
