M(NO3)2(M = Cd, Co)与间苯二甲酸(1,3-H2bdc)和N-(吡啶-2-基)-N-{4-[2-(吡啶-4-基)乙烯基]苯基}吡啶-2-胺(ppvppa)在150℃下发生溶剂热反应，得到两种二维(2D)配位聚合物(CP) [M(ppvppa)2(1,3-bdc)]·xH2O [M = Cd,x= 2 (1·2H2O); M=Co,x=1.5(2·1.5H2O)]。在1和2中，ppvppa的不配位二(吡啶-2-基)胺可以进一步结合额外的金属离子。他们的AgI掺杂聚合物[Cd(ppvppa)2(1,3-bdc)]·AgNO3(1a)和[Co(ppvppa)2(1,3-bdc)]·0.75AgNO3(2a)是通过分别将1和2浸入AgNO3水溶液中获得的。与1和2相比，1a和2a由于其带隙更窄，对水中RhB、酸性红27和茶碱的光降解表现出大大增强的催化活性。对于2a，三种污染物的光分解表观速率常数分别比2大约4.4、2.3或1.76倍。研究结果为金属离子掺杂策略提供了见解，该策略可以缩小CP的带隙，从而大大提高其降解水中有机污染物的光催化性能。
Solvothermal reactions of M(NO3)2(M = Cd, Co) with isophthalic acid (1,3‐H2bdc) andN‐(pyridin‐2‐yl)‐N‐{4‐[2‐(pyridin‐4‐yl)vinyl]phenyl}pyridin‐2‐amine (ppvppa) at 150 °C afforded two two‐dimensional (2D) coordination polymers (CPs) [M(ppvppa)2(1,3‐bdc)]·xH2O [M = Cd,x= 2 (1·2H2O); M = Co,x= 1.5 (2·1.5H2O)]. In1and2, the uncoordinated di(pyridin‐2‐yl)amine of ppvppa can further bind additional metal ions. Their AgI‐doped polymers, [Cd(ppvppa)2(1,3‐bdc)]·AgNO3(1a) and [Co(ppvppa)2(1,3‐bdc)]·0.75AgNO3(2a), were obtained by immersing1and2, respectively, into an aqueous solution of AgNO3. Compared with1and2,1aand2aexhibited greatly enhanced catalytic activity towards the photodegradation of RhB, Acid Red 27, and theophylline in water due to their narrower band gaps. For2a, the apparent rate constants for the photodecomposition of the three pollutants are around 4.4, 2.3, or 1.76 times larger than those of2, respectively. The results provide an insight into a metal‐ion doping strategy that can narrow the band gaps of the CPs and thus greatly improve their photocatalytic performance in degrading organic pollutants in water.
