title: Fabrication of Ag/CPs composite material, an effective strategy to improve the photocatalytic performance of coordination polymers under visible irradiation.
abstract: To enhance the photocatalytic property of coordination polymers (CPs) in the visible light region, Ag loaded coordination polymer composite materials (Ag/CPs) were synthesized successfully through a photoreduction reaction of Ag(+) on the surface of CPs. Photoluminescence (PL) was used to investigate the separation of photogenerated electron-hole pairs and the results illustrated Ag/CPs display higher quantum yields than CPs. This can be attributed to the strong interactions between Ag nanorods and coordination polymers, which lead to electron-hole pair separation between Ag nanorods and CPs. The degradation of Rhodamine B (RhB) was investigated to study the photocatalytic activities. Ag/CPs exhibited excellent photocatalytic activity in the UV and visible light region, while CPs can only decompose RhB under the irradiation of UV light. Furthermore, Ag/CPs showed outstanding stability during degradation of RhB.
