Abstract

Polyvinyl chloride (PVC) plastics are widely applicable in our daily life; however, their overuse and extremely high resistance to recycling/disposal have caused serious challenges to our environment. In this study, we proposed an effective and green method to convert PVC plastics to carbonaceous materials via KOH-assisted room-temperature dehalogenation, along with the formation of clean byproducts of KCl and H 2 O. Thereof, high-quality porous carbon materials are obtainable through performing simple annealing on the above-mentioned carbonaceous materials. The as-resulted carbon materials derived from PVC plastics were fabricated into electrodes for supercapacitor application. Remarkably, the porous carbon material derived from PVC plastic wrap (PW-C) exhibited excellent performance for aqueous symmetric supercapacitor. The specific capacitance reached up to 399 and 363 F g –1 (at 1.0 A g –1 ) in 6.0 mol L –1 KOH and 1.0 mol L –1 H 2 SO 4 electrolytes, respectively. Meanwhile, PW-C showed very good rate capability and cycling stability in both electrolytes. Therefore, our developed method is capable of treating PVC plastic wastes safely and efficiently and converting them into valued-added porous carbon electrode materials, which may find very soon practical implantations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
