synthesis of cyano-bridged Cu (I)/Cu (II) complexes usually requires organometallic catalysts or is carried out under high-temperature and high-pressure conditions. Herein, the cyano-bridged two-dimensional Cu (I)/Cu (II) photocatalyst, [Cu (Py)(CN)] (), is synthesized at room temperature. The synthesis mechanism of shows that the partial Cu (II) complex catalyzed the C-C bond cleavage of 1,3-isophthalonitrile (L) to introduce -CN and generate Cu (I)/Cu (II). Its ultrathin nanosheets can be obtained by adding sodium dodecyl benzene sulfonate and performing ultrasonic synthesis in the process of synthesis . The ultrathin nanosheets of have a lattice distance of about 0.31 nm, and it can rapidly decompose methylene blue (MB) (K = 0.25 mg L min at pH = 3). This research work is beneficial for synthesis of cyano-bridged Cu (I)/Cu (II) complexes at room temperature and explores their synthesis and photocatalytic mechanism.
氰基桥联的Cu (I)/Cu (II)配合物的合成通常需要有机金属催化剂，或在高温高压条件下进行。在此，氰基桥联的二维Cu (I)/Cu (II)光催化剂[Cu (Py)(CN)] ()在室温下合成。其合成机理表明，部分Cu (II)配合物催化1,3-间苯二甲腈(L)的C-C键断裂以引入-CN并生成Cu (I)/Cu (II)。在合成过程中，通过添加十二烷基苯磺酸钠并进行超声合成可得到其超薄纳米片。的超薄纳米片的晶格间距约为0.31 nm，并且它能快速分解亚甲基蓝(MB)(在pH = 3时K = 0.25 mg L min)。这项研究工作有利于在室温下合成氰基桥联的Cu (I)/Cu (II)配合物，并探索其合成及光催化机理。
