Abstract

Waste plastics collected from local food courts were catalytically pyrolyzed and decomposed to produce carbon nanomaterials (CNMs) as well as hydrogen-rich gases as byproducts in this work. A series of bimetallic catalysts: Co–Fe, Co–Ni, and Fe–Ni with MgO as the catalyst support were synthesized and compared for the process. Products including high value-added carbon nanomaterials and gases were characterized to evaluate the activity of each bimetallic catalyst. In addition, products from four types of plastic: LDPE-plastic bags for bagging, PP-plastic bottles for drinking, PS-plastic lids, and PET-mineral water bottles were further comprehensively compared in terms of yield, purity of carbon, and adsorption capacity. Results show that Fe–Ni–Mg prepared by the pH-increase precipitation method exhibited the best performance for plastic conversion, contributing to the maximum CNM yield of 30.25 wt % and hydrogen yield of 31.52 mmol/g plastic . However, the Co–Ni/MgO synthesized by impregnation gave the least activity. Regarding the different plastic types, plastic waste from LDPE bags produced hydrogen with a relatively high yield of 35.27 mmol/g plastic, while PS lid plastic resulted in a relatively high CNM yield of 38.26 wt %. It is also found that the PET bottle was not suitable for CNM production accompanied by a high content of CO 2 in product gases. The CNMs were further applied as adsorbents for wastewater treatment. The plastic-derived CNMs show strong (∼180 mg/g CNM ) adsorption capacity of metal cations such as Fe, Ag, and Ni.

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.
