金属有机骨架材料(MOFs)是一种重要的功能材料,通过原位电化学合成方法在离子液体1-丁基-3-甲基咪唑氯盐作为模板剂的条件下合成MOF-5(IL)(Zn4O(BDC)(BDC=1,4-苯二甲酸)。π-π堆叠作用、离子键和配位键的相互作用使得MOF-5(IL)形成球状结晶。分析结果表明:通过电化学法在离子液体中合成的MOF-5(IL)比传统溶剂热法合成的MOF-5表现出更好的结晶性和更高的热稳定性。循环伏安曲线显示该电化学合成反应是一个扩散控制的不可逆过程。对甲基橙的降解实验表明,MOF-5(IL)独特的结构特征可以提高Bi OBr的光催化活性。因此,MOFs材料可以取代贵金属来提高卤氧铋的光催化性能。
MOFs (MOFs) are an important functional material for the synthesis of MOF-5 (IL) by in situ electrochemical synthesis using 1-butyl-3-methylimidazolium chloride as a template. (BDC) (BDC = 1,4-phthalic acid). The interaction of π-π stacking, ionic bond and coordination bond leads to the formation of spherical crystals of MOF-5 (IL) The synthesis of MOF-5 (IL) in ionic liquid showed better crystallinity and higher thermal stability than traditional solvothermally synthesized MOF-5. The cyclic voltammetry showed that the electrochemical reaction was a The irreversible process of diffusion control.Degradation of methyl orange showed that the unique structural characteristics of MOF-5 (IL) can improve the photocatalytic activity of Bi OBr.So, MOFs can replace the noble metal to improve the photocatalytic activity of bismuth oxyhalide .
