New approaches to the degradation of organic dyes, and nitro- and chloroaromatics using coordination polymers as photocatalysts

Industrial wastewater with organic pollutants has become one of the most serious problems related to our human environment. One possible treatment is to develop environmentally friendly and efficient photocatalysts. Coordination polymers (CPs) with a structural regularity and synthetic stability provide an important possibility to perform photodegradation. Doping CPs with metal ions or loading CPs on carbon nanomaterials can extend their photoresponse region and thus enhance their catalytic activity toward the photodegradation of organic dyes. In this article we briefly highlight some of the latest progress in the photodegradation of organic dyes using modified CP-based catalysts. The decomposition of nitro and chloroaromatics using CPs as photocatalysts is also described.

含有有机污染物的工业废水已成为与人类环境相关的最严重问题之一。一种可能的处理方法是开发环保且高效的光催化剂。具有结构规整性和合成稳定性的配位聚合物（CPs）为进行光降解提供了一种重要的可能性。用金属离子掺杂CPs或把CPs负载在碳纳米材料上能够拓宽其光响应区域，从而提高其对有机染料光降解的催化活性。在本文中，我们简要强调了使用改性的基于CP的催化剂对有机染料进行光降解的一些最新进展。还描述了使用CPs作为光催化剂对硝基和氯代芳香族化合物的分解。
