Abstract

Converting waste plastics into high-value carbon materials is one of the most promising solutions for upcycling the waste resources and significant environmental concern. Herein, we have enhanced the carbonization yield through a designed one-step strategy involving the pre-mixing of KOH with consumed polyethylene terephthalate (PET). It was further applied to the co‑carbonization of consumed PET with woody biomass waste to produce functional carbon materials. The carbon materials exhibit remarkable adsorption capabilities, achieving up to 529.3 mg/g for methylene blue and 368.5 mg/g for methyl orange, as well as significant adsorption capacity of 3.03 mmol/g for CO₂, which are much higher than many reported adsorbents. This work proposes a facile method for upcycling consumed PET and woody biomass waste, presenting a significant strategy for achieving high-valuable potential application.

期刊介绍： Sustainable Materials and Technologies (SM&T), an international, cross-disciplinary, fully open access journal published by Elsevier, focuses on original full-length research articles and reviews. It covers applied or fundamental science of nano-, micro-, meso-, and macro-scale aspects of materials and technologies for sustainable development. SM&T gives special attention to contributions that bridge the knowledge gap between materials and system designs.
