Bimetallic solutions play a vital role in the growth and functionality of copper trimesate (Cu-BTC) metal-organic frameworks (MOFs). The effect of Ag, Ca, Mn, Co, and Zn on the growth of Cu-BTC was studied by fabricating M-Cu-BTC MOFs at room temperature using bimetallic M-Cu solutions. While Ag in the MOF had a rod-like morphology and surface properties, divalent cations deteriorated it. Moreover, unconventional Cu presence in the MOF formed a new building unit, which was confirmed in all the MOFs. Apart from Ag and Mn, no other MOF showed any presence of secondary cations in the structure. While Ag-Cu-BTC showed an improved HS uptake capacity, other M-Cu-BTC MOFs had superior organic pollutant adsorption behavior. Thus, we have demonstrated that the physicochemical properties of Cu-BTC could be modified by growing it in bimetallic solutions.
双金属溶液在均苯三甲酸铜（Cu-BTC）金属有机框架（MOF）的生长和功能方面起着至关重要的作用。通过在室温下使用双金属M-Cu溶液制备M-Cu-BTC MOF，研究了Ag、Ca、Mn、Co和Zn对Cu-BTC生长的影响。虽然MOF中的Ag具有棒状形态和表面性质，但二价阳离子使其恶化。此外，MOF中非常规的Cu存在形成了一个新的构建单元，这在所有MOF中都得到了证实。除了Ag和Mn外，没有其他MOF在结构中显示出任何二次阳离子的存在。虽然Ag-Cu-BTC显示出提高的HS吸收能力，但其他M-Cu-BTC MOF具有优异的有机污染物吸附行为。因此，我们已经证明，通过在双金属溶液中生长Cu-BTC，可以改变其物理化学性质。
