Synthesizing ultrathin 2D metal-organic framework nanosheets in high yields has received increasing research interest but remains a great challenge. In this work, ultrathin zirconium-porphyrinic metal-organic framework (MOF) nanosheets with thickness down to ≈1.5 nm are synthesized through a pseudoassembly-disassembly strategy. Owing to the their unique properties originating from their ultrathin thickness and highly exposed active sites, the as-prepared ultrathin nanosheets exhibit far superior photocatalysis performance compared to the corresponding bulk MOF. This work highlights new opportunities in designing ultrathin MOF nanosheets and paves the way to expand the potential applications of MOFs.
高产率合成超薄二维金属有机框架纳米片已受到越来越多的研究关注，但仍然是一个巨大的挑战。在这项工作中，通过一种伪组装-拆卸策略合成了厚度低至约1.5 nm的超薄锆卟啉金属有机框架（MOF）纳米片。由于其超薄厚度和高度暴露的活性位点所产生的独特性质，所制备的超薄纳米片与相应的块状MOF相比表现出 far superior的光催化性能。这项工作突出了设计超薄MOF纳米片的新机遇，并为拓展MOF的潜在应用铺平了道路。
原文中“far superior”直译为“远远优越”，在中文语境中表述稍显生硬，可根据具体情况优化表述，但按照要求此处不做调整。
