面对能源危机,金属基量子点(QDs)成为高性能超级电容器(SCs)材料的重要研究方向。其制备方法多样,包括溶剂/水热合成法、微波辅助合成法等。目前,金属氧/硫/氮化物QDs、金属单质QDs以及新兴的MXene QDs等多种类型的QDs已广泛应用于高性能SCs材料领域。它们常与碳基材料、导电聚合物以及金属有机框架等其他材料复合进行改性。然而,金属基QDs在SCs中的使用仍面临着合成过程复杂、界面结合不牢固、合成成本高等诸多挑战。未来,随着金属基QDs的研发合成更简化、经济效益化,界面结合也将更为紧密,持续推进金属基QDs在SCs中的市场应用化进程。
In response to the energy crisis,metal-based quantum dots (QDs) have emerged as a significant research direction for high-performance supercapacitor (SCs) materials.Various preparation methods are employed,including solvent/hydrothermal synthesis and microwave-assisted synthesis.Currently,a wide array of QDs,such as metal oxide/sulfide/nitride QDs,metallic elemental QDs,and the emerging MXene QDs,are utilized across the vast field of high-performance SCs materials.These QDs are often combined with other materials such as carbon-based materials,conductive polymers,and metal-organic frameworks (MOFs) for performance enhancement.However,the application of metal-based QDs in SCs still faces numerous challenges,including complex synthesis processes,weak interfacial bonding,and high synthesis costs.Future research aims to simplify and economize the synthesis of metal-based QDs,enhance interfacial bonding,and accelerate their market application in SCs.
