Its toxicity poses a significant risk, particularly to young children, leading to lifelong severe health issues. Detecting lead is crucial, and there is increasing interest in adopting eco-friendly approaches, such as utilizing carbon dots (CDs) derived from biomass. In our present study, we have synthesized CDs from peanut shells (PNS) through a straightforward pyrolysis process and employed various techniques to characterize these PNS-based CDs. Our findings reveal that these CDs emit fluorescence at 455 and 574nm when excited at 285nm, particularly in the presence of nanomolar Pb2+ ions. Notably, these PNS-derived CDs (PNS-CDs) demonstrate remarkable sensitivity and selectivity for detecting Pb2+ ions. A limit of detection (LOD) of 16.59nM was determined for the sensor, corresponding to a linear concentration range of 16.622.2nM. This study proposes a novel and simple one-pot pyrolysis method to synthesize CDs from PNS for the rapid testing of lead contamination in the environment, which holds great promise for sensor applications. 2025 Wiley-VCH GmbH.
