High Quantum Yield Nitrogen-Carbon Dots (N-CDs) from Plastic Waste

: A high quantum yield of up to 20% N-CDs from plastic bag waste has been synthesized via the pyrolysis-hydrothermal method. Using plastic bag waste as a carbon source offers several advantages, including their abundant availability, low cost, and potential to reduce plastic waste in the environment. The effect of hydrothermal time and H 2 O 2 concentration as an oxidant was evaluated. The N-CDs acquired exhibit a consistent blue fluorescence, possess an average dimension of 5.94 nm, and consist of graphitic structures that may contain flaws induced by surface functional groups such as amine, imine, alcohol, carboxyl, and carbonyl. Excellent stability of the resulting N-CD toward storage time, NaCl, and phosphate buffered salt (PBS) solution pave the way to possible applications for metal ions sensing in wastewater and human cells.

期刊介绍： “Evergreen - Joint Journal of Novel Carbon Resource Sciences & Green Asia Strategy” is a refereed international open access online journal, serving researchers in academic and research organizations and all practitioners in the science and technology to contribute to the realization of Green Asia where ecology and economic growth coexist. The scope of the journal involves the aspects of science, technology, economic and social science. Namely, Novel Carbon Resource Sciences, Green Asia Strategy, and other fields related to Asian environment should be included in this journal. The journal aims to contribute to resolve or mitigate the global and local problems in Asia by bringing together new ideas and developments. The editors welcome good quality contributions from all over the Asia.
