In this work, copper-based metal organic frameworks Cu₃(BTC)₂ (BTC = 1,3,5-benzenetricarboxylatle), were applied in the conversion of toxic oxynitride into nitrogen at low temperature. Scanning electron microscope (SEM), thermal gravimetric analysis (TGA), X-ray photoelectron spectroscopy (XRD) and other characterization methods were employed to fully understand the properties of the catalysts. We introduced acetic acid into the synthesis process as the modulator of the crystal structure and morphology. The catalytic assessment indicated that compared with the prototype, modified Cu-MOFs materials obtain enhanced catalytic activity for the SCR reaction. Besides, several thermolysis experiments were conducted to explain structure–function relationship.

在这项工作中，铜基金属有机骨架Cu ₃（BTC）₂（BTC = 1,3,5-苯三甲酸）被用于在低温下将有毒的氮氧化物转化为氮。使用扫描电子显微镜（SEM），热重分析（TGA），X射线光电子能谱（XRD）和其他表征方法来充分理解催化剂的性能。我们将乙酸引入到合成过程中，作为晶体结构和形态的调节剂。催化评估表明，与原型相比，改性的Cu-MOFs材料对SCR反应具有增强的催化活性。此外，进行了几次热解实验以解释结构与功能的关系。
