Mechanochemical synthesis is recognized as a general synthetic technique that is an alternative to conventional solvent-intensive methods. The mechanochemical synthesis of metal-organic frameworks (MOFs) adsorbents of great industrial potential like UTSA-280 is of great interest and significance. In this work, UTSA-280 was synthesized from the easily accessible calcium oxide (CaO) or calcium hydroxide (Ca(OH)₂) and raw squaric acid (SA) through mechanochemical synthesis at room temperature. This environment-friendly method has been validated by experiments of powder X-ray diffraction patterns, scanning electron microscope and gas sorption.

乙烯筛UTSA-280的机械化学合成

机械化学合成是公认的常规合成技术，可替代常规溶剂密集型方法。具有巨大工业潜力的金属-有机骨架（MOFs）吸附剂的机械化学合成，如UTSA-280，具有极大的兴趣和意义。在这项工作中，UTSA-280是在室温下通过机械化学合成由容易获得的氧化钙（CaO）或氢氧化钙（Ca（OH）₂）和粗方酸（SA）合成的。通过粉末X射线衍射图谱，扫描电子显微镜和气体吸附实验验证了这种环境友好的方法。
