Abstract：
As water pollution and scarcity pose severe threats to the sustainable progress of human society, it is important to develop a method or materials that can accurately and efficiently detect pollutants and purify aquatic environments or exploit marine resources. The compositing of photoluminescent and hydrophilic carbon dots (CDs) with hydrogels bearing three-dimensional networks to form CD-hydrogel composites to protect aquatic environments is a \"win-win\" strategy. Herein, the feasibility of the aforementioned method has been demonstrated. This paper reviews the recent progress of CD-hydrogel materials used in aquatic environments. First, the synthesis methods for these composites are discussed, and then, the composites are categorized according to different methods of combining the raw materials. Thereafter, the progress in research on CD-hydrogel materials in the field of water quality detection and purification is reviewed in terms of the application of the mechanisms. Finally, the current challenges and prospects of CD-hydrogel materials are described. These results are expected to provide insights into the development of CD-hydrogel composites for researchers in this field.
摘要：
由于水污染和水资源短缺对人类社会的可持续发展构成严重威胁,重要的是开发一种方法或材料，可以准确有效地检测污染物，净化水生环境或开发海洋资源。光致发光和亲水性碳点（CD）与具有三维网络的水凝胶复合形成CD-水凝胶复合材料以保护水生环境是一种“双赢”策略。在这里，证明了上述方法的可行性。本文综述了CD-水凝胶材料在水生环境中的研究进展。首先,讨论了这些复合材料的合成方法，然后,根据不同的原料组合方法对复合材料进行分类。此后,从机理的应用方面综述了CD-水凝胶材料在水质检测和净化领域的研究进展。最后,阐述了CD-水凝胶材料的当前挑战和前景。这些结果有望为该领域的研究人员提供有关CD-水凝胶复合材料开发的见解。
