ABSTRACT

Carbon materials (CMs) with adjustable composition, morphology, and porosity have great scientific and technological significance and have long been regarded as key components for the construction of sustainable and clean energy devices (such as fuel cells, batteries, and supercapacitors). The current synthetic strategies for CMs mainly rely on the defunctionalization of organics containing H-, O-, N-, or S-moieties, while halogen-functionalized organics are much less explored. Since halogenated polymers such as polyvinyl chloride (PVC) are overwhelmingly used and extremely hard to recycle, it is of great importance to develop efficient methods for recycling halogenated polymeric wastes, especially PVC wastes. In this chapter, we first introduce the principles and advantages of using halogenated polymer wastes as carbon sources. After that, the efficient methods and techniques for adjusting the composition, morphology, and porosity of CMs produced using halogenated polymers are summarized. Demonstrative electrochemical applications of halogenated polymer-derived functional CMs are provided, and in the end, the perspectives of halogenated polymer wastes for environmental protection and high-quality functional CMs are given.
