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@_monoZIF‐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.

坚固的金属有机骨架的溶胶-凝胶合成，用于纳米颗粒封装

提出了一种新型的复合材料，涉及将氧化锡纳米颗粒（SnO ₂ -NPs）原位固定在整体金属-有机骨架（MOF）中，即沸石咪唑酸酯骨架（ZIF）-8。SnO ₂ @ _mono ZIF-8利用了纳米颗粒MOF的机械性能，结构弹性和高密度，同时利用了纳米颗粒的光催化作用。该复合材料显示出出色的光催化性能，代表了有毒废水处理领域的关键进展，并且对于商业应用而言是至关重要的验证。至关重要的是，在十个催化循环后观察到催化活性的完全保留。
