Abstract

Industrial wastewater with pollutants is one of the most overwhelming problems related to the ecological environment and human health. Although several traditional methods including adsorption, precipitation, and coagulation are widely used to decompose pollutants in wastewater, they have potential limitations and deficiencies. Therefore, developing green and efficient photocatalysts is the goal of environmental scientists and chemists. Coordination polymers (CPs), a class of crystalline inorganic–organic hybrid materials, can work as heterogeneous photocatalysts to destroy such pollutants efficiently. Due to their structural adjustability and synthetic stability, the absorption band can be fine-tuned, which extends the absorption of light from UV to UV-visible to the visible region. Doping metal ions into the CP frameworks is also a useful strategy to narrow the bandgap, thus greatly improving their photocatalytic activities. Core-shell-like CP-based photocatalysts are also developed. Based on their synergistic effects, these composites exhibited superior photocatalytic activity and high stability in decomposing pollutants. In this Chapter, we summarize some advances on pristine CPs, ion-doped CPs, and core-shell-like CP-based materials as self-supported photocatalysts for their green and efficient degradation of organic dyes in water.
