提出了一种新型复合材料，涉及将氧化锡纳米颗粒（SnO2-NPs）原位固定在整体金属有机骨架（MOF）内，咪唑沸石骨架（ZIF）-8。 SnO2@(mono)ZIF-8 利用整体 MOF 的机械性能、结构弹性和高密度，同时利用纳米颗粒的光催化作用。该复合材料表现出出色的光催化性能，代表了有毒废水处理领域的重大进步，也是商业应用的重要验证。至关重要的是，十次催化循环后观察到催化活性完全保留。
A new type of composite material involving the in situ immobilization of tin oxide nanoparticles (SnO2-NPs) within a monolithic metal-organic framework (MOF), the zeolitic imidazolate framework (ZIF)-8 is presented. SnO2@(mono)ZIF-8 exploits the mechanical properties, structural resilience, and high density of a monolithic MOF, while leveraging the photocatalytic action of the nanoparticles. The composite displays outstanding photocatalytic properties and represents a critical advance in the field of treating toxic effluents and is a vital validation for commercial application. Crucially, full retention of catalytic activity is observed after ten catalytic cycles.
