However, these often encounter substantial economic environmental challenges their implementation. An increasingly attractive alternative is chemical upcycling, which can transform plastics value-added chemicals. This review systematically examines upcycling applicable major commercial plastics, including polyethylene terephthalate (PET), polyolefins, polystyrene (PS), polyvinyl chloride (PVC). We focus on key strategies such as solvolysis, catalytic pyrolysis, hydrocracking hydrogenolysis, along with some emerging approaches electrocatalysis photooxidation, aiming summarize trends plastics.

The surge in waste plastics has placed a serious burden on the global ecosystem. Traditional recycling methods are insufficient to handle growing volume of plastic waste, highlighting urgent demand for innovative technologies. Transforming into high-value carbon nanomaterials is simple and efficient resource recovery strategy, especially effective handling mixed or hard-to-separate waste. This method not only simplifies sorting discarded but also offers significant advantages efficiency processing convenience. review systematically summarized various technologies converting nanomaterials, focusing catalytic mechanisms different conversion methods. We analyzed how catalysts, temperatures, metal-support interactions affect yield quality nanomaterials. Additionally, potential applications environmental remediation, energy storage, catalysis evaluated. ongoing challenges future research directions this field critically discussed, which will ultimately facilitate more from contribute realization circular economy. believe that inspire creativity designing such win-win reaction systems realize "waste treat waste" concept.
